hello mate, something new to test, we do not want to migrate nethserver-roundcubemail-next (from Nethforge, no worry, manual dump can been done) so we have changed the way how to detect nethserver-roundcubemail from nethserver-roundcubemail-next
The test is quite simple and is written here: Roundcubemail migration From NS7 to NS8 · Issue #6851 · NethServer/dev · GitHub
If you could help by testing and report to the bug report, thank in advance
