Issue No version above 18.0.28 available for upgrade

[exit15]

Hi,
Brand new server, came with 18.0.25 and I was able to upgrade to 18.0.28 using the interface, but there is no option for anything higher than that. Normally I wouldn't care, but I am trying to migrate from another plesk server that runs version 18.0.29 (the update screen gives the option to upgrade further to 18.0.30). Does it have to do with the OS? is there a way to force the upgrade.
Error message from migration tool:
Version of Plesk on the target server (18.0.28) is lower than version of Plesk on the source server 'source' (18.0.29). Migration to lower version of Plesk is not supported by migration tool.

Target server:

CPU	Intel Core Processor (Haswell, no TSX) (4 core(s))
Version	Plesk Obsidian v18.0.28_build1800200720.10 os_Debian 8.0
OS	Debian 8.11

Source server:

CPU	Intel(R) Xeon(R) CPU E5-2683 v3 @ 2.00GHz (2 core(s))
Version	Plesk Obsidian v18.0.29_build1800200825.21 os_CentOS 7
OS	CentOS Linux 7.8.2003 (Core)

Your target server uses Debian 8, which is not supported by Plesk anymore (so no new versions). See also Feature Deprecation Plan

I suggest using a more modern OS supported by Plesk, such as Debian 10 or 9.

Thanks a lot. Working with the host to upgrade/change OS

Good thing this came up before going through the process of migrating, otherwise you would find yourself needing to migrate again in the near future!
