Linux and Windows Server administration

Reliable systems come from steady, careful administration: patches applied, backups verified, access controlled and changes documented. WITSB handles that work remotely, as a project or on a retainer.

Questions

Can you upgrade an old server without downtime?

Often, yes, or with a short planned window. We take backups first, test the upgrade path and keep a rollback option ready.
