I’m just in the final throws of installing a new Alma host to replace my existing C7 one. The timeline was:
- 2019 - Create CentOS8 VM as a test
- 2020 - Move OwnCloud and Dokuwiki to C8 VM. Test DNS. Create a temporary host C8 system to test for hardware issues
**Create Springdale, SuSE VMs to start evaluating moving away from CentOS
**Create Alma VM when the beta came out
**Update Alma VM to release.
**Create an Alma USB stick to test on the Laptop (can’t change the OS on it, SWMBO requires Windows).
**Create a full installation of Alma on the host.
**Mount the original /virt filesystem (where my VMs are kept)
**Configure virtual machines onto the new host.
**Mount the original /home directory on the new host.
and now I’m running an Alma host with a C8 VM. Applications can be moved back to the host in slow time whilst I maintain service to the other nodes. Phew!
Thanks all, the combined upgrade and migration has gone with minimal problems.
