Because of PHP security problems from October 2026 I should upgrade my servers to actual versions of OS.

My servers - see My servers.

Plan:

• - define which servers are there
  • 185.194.236.66
  • 94.199.215.198
  • 185.162.250.65 (not more necessary → can be terminated)
  • 202.61.247.140
• - define in which order they should be upgraded
  • 202.61.247.140 by netcup (avril2021.avril.work)
  • 185.194.236.66 by IP-Projects (avril2019.wialon-consulting.de)
  • 94.199.215.198 by IP-Projects (relay / vwiki / www.avril.work)
  • 185.162.250.65 by netcup (not more necessary → can be terminated)
