Take over and stabilise organically grown Linux servers
When documentation is missing, versions are outdated, or the previous administrator is unavailable, we first establish transparency. We then stabilise the estate and accept only a technically manageable scope.

Takeover model
Audit first, ongoing operations second
The audit price covers one standard Linux instance. Larger estates with multiple servers, unknown dependencies, or end-of-life components are assessed first. The ongoing contract starts only after the takeover boundary is documented.
No blind operations in an unknown estate
Operational takeover begins with reliable information about systems, access, data, dependencies, and recovery, not with an immediate maintenance contract.
Preserve knowledge
Servers, services, cron jobs, certificates, access, domains, and external dependencies are documented.
Stabilise operations
Critical security, backup, and capacity risks are prioritised without unnecessary changes to the live system.
Make replacement plannable
Non-viable components receive an incremental modernisation or migration path instead of a risky big-bang rebuild.
What we clarify before standard operations
The audit separates immediate operating risks from planned technical debt.
Inventory and dependencies
Capture servers, operating systems, applications, databases, network paths, and external services.
Access and permissions
Organise administrative accounts, keys, provider access, and technical ownership.
Updates and support status
Document EOL versions, package sources, manual changes, and possible upgrade paths.
Backup and restore
Assess backups, retention, external failure domains, and actual recoverability.
Monitoring and capacity
Expose missing signals, resource constraints, certificates, and recurring incidents.
Modernisation needs
Separate stable components from parts that require replacement and risky one-off connections.
One operating model for Your organically grown Linux environment and additional systems
The provider is only one operating location. WZ-IT connects servers, clouds, and on-premises systems into a documented environment with consistent monitoring, controlled access, and one coordinated service level.
Location and control
Contracts, accounts, and administrative control remain with you. We take over the agreed technical operations without moving the infrastructure into a closed hosting product.
Private connectivity
NetBird, WireGuard, or existing site connections integrate further clouds, Proxmox systems, and on-premises networks through controlled paths.
Operations and response
Monitoring, updates, backups, documentation, and incident response are designed across all participating systems and operated according to the selected service level.
Calculate server operations by quantity and service level
Select the number of systems and the required response target. Systems remain with your provider, in your cloud account, or on premises.
Managed servers
Physical or virtual Linux servers in an existing customer infrastructure.
Progressive pricing per coherent customer environment: first server €149.90, servers 2–5 €119.90 each, servers 6–10 €99.90 each. From server 11 we provide a custom offer.
Takeover boundary
Unknown risks are not silently inherited
Ongoing operations begin after prioritised immediate actions and a documented responsibility matrix. Irreparable technical debt, missing vendor support, and non-recoverable systems are identified explicitly.
Prepare the takeoverFrom an unknown estate to controlled operations
Takeover follows clear steps so the live service is not endangered by unnecessary changes.
- 01
Inventory
Capture systems, services, data, access, and dependencies.
- 02
Stabilise
Resolve critical security, backup, and capacity risks by priority.
- 03
Document operations
Establish monitoring, maintenance, escalation, and responsibility boundaries.
- 04
Modernise incrementally
Replace technical debt in a controlled order based on risk and business value.
Enquiry
Assess takeover of a legacy Linux system
Briefly describe the systems, previous owner, and immediate trigger. Access credentials are not required for the initial assessment.
Frequently asked questions about legacy Linux server takeover
Audit, transitional operations, and modernisation
Yes, when a technical inventory is possible. Missing documentation increases the initial assessment and transition effort.
We inventory reachable systems and accounts, clarify provider access, and establish controlled administrative access. Ownership and authorisation must be resolved by the client.
No. We first assess dependencies and fallback paths. Unverified updates can endanger an organically grown system more than a short controlled transition.
Only with documented risk, technical safeguards, and an agreed replacement path. Standard service-level commitments may not be possible for some versions.
We review backup sources, retention, and dependencies. Restore tests are planned separately based on data volume and available test methods.
No. Stable components can remain. We replace first what genuinely limits security, operations, or extensibility.
Application operations and development can be added but are assessed separately from Linux server responsibility.
For an unknown estate, a server audit creates the prioritised foundation for immediate action, standard operations, and modernisation.

“WZ-IT's advice on our Azure migration was technically sound and completely non-binding right from the intro call - we took away a great deal.”
Operations that visibly relieve customers
Customer feedback on monitoring, updates, maintenance, support and stable production systems.
“WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.”
Steve Kirchner
Managing Director, nextGYM GmbH
“Professional, honest and technically thoroughly sound: WZ-IT set up our Proxmox and backup infrastructure securely and future-proof. The consulting from Timo and Robin was objective and needs-driven, the implementation smooth and the final documentation exemplary. You can tell immediately that business-critical infrastructure is thought through holistically from the outset here and implemented with clear ownership.”

Stadtwerke Brühl - municipal energy and infrastructure utility.
“WZ-IT provided very competent support in implementing our server and virtualization infrastructure. As part of the project, a Proxmox-based virtualization environment was set up along with a virtual machine for our application systems. Additionally, a structured backup concept was implemented. A particular focus was on security: the setup of a VPN tunnel and the clean implementation of encryption and access concepts were professionally executed. The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT.”

“WZ-IT manages our Proxmox cluster reliably and professionally. The team handles continuous monitoring and regular updates for us and responds very quickly to any issues or inquiries. They also configure new nodes, systems, and applications that we need to add to our cluster. With WZ-IT's proactive support, our cluster and the business-critical applications running on it remain stable, and high availability is consistently ensured. We value the professional collaboration and the noticeable relief it brings to our daily operations.”

“Communication with WZ-IT was open, friendly and professional from the very beginning. Mr. Wevelsiep and Mr. Zins responded to every one of our questions patiently, promptly and respectfully, and contributed their own suggestions and good ideas on how to modernize our server infrastructure and adapt it even better to our needs. Throughout, WZ-IT consistently kept our need for data sovereignty and GDPR compliance in mind. Even short-notice adjustments and change requests from our side were implemented quickly and patiently and integrated consistently into the overall concept. From planning to the final handover, every step was documented transparently and comprehensively - so if a provider change should ever become necessary, the documentation would let us onboard a successor into our infrastructure very quickly. We are extremely satisfied with WZ-IT and hope to continue working together for a long time.”
