Hello dear RC testers!
We are releasing 7.5.0 final today, so here's how to go from 7.5.0RC to 7.5.0.
Warning: this is only for people who installed the RC. Detailed procedure will be given in the release announcement for upgrading an XCP-ng 7.4 server
Option 1, upgrade using the installation ISO
Will work, although may be a little overkill since you already have a nearly-final 7.5.0.
Option 2, update yum repository files and update the system
# remove the RC-specific repository file if present
rm /etc/yum.repos.d/xcp-ng-7.5.repo -f
# install the 7.5 official repository file
wget https://updates.xcp-ng.org/7/xcp-ng-7.5.repo -O /etc/yum.repos.d/xcp-ng.repo
# update. If you had updated your RC regularly, this will install nothing, else you'll get a few packages
yum update
# if the kernel or xen-* packages got updated, reboot your server
# that's it, you've got 7.5.0 final!
