We will be migrating our PRTG installation to a new server soon. We currently use the 'preview' release channel on version 220.127.116.114. When I go to pull down the installation it is the 'stable' release of 18.104.22.1685. When migrating to the new server would it be best practice to install the other instance of PRTG, upgrade using auto update, upgrade the existing server to the same version, and then perform the migration? Or is there a repository of all recent versions so we can download and match?
