this is a general question -and may be you already have a tutorial or manual for it - i could not find.
Story: when migrating to J4 - normally Backup 8.X hast to be replaced - also Admin Tools -
I had it now - that after installing new Akeeba Backup and Admin tools my page collapsed. Of course i did sth. wrong - but no idea what. So my idea was to ask the professionals .)
I now updated Akeeba Backup to 9.-X and in Akeeba BAckup there was a button that said: migrate settings. I did it. Then a button came: see what to uninstall and i uninstalled what was shown me there.
BUT - when i did that: The first "failure"came up saying:
You have 1 extension(s) depending on this version of Akeeba FEF. The package cannot be uninstalled unless these extensions are uninstalled first.
You have 5 extension(s) depending on this version of FOF. The package cannot be uninstalled unless these extensions are uninstalled first.
So... shell i search for FOFO or FEF and de install those?
After that i stopped proceeding with akeeba Admin Tools - i am afraid i will "kill" the system again. :)
It would be perfect to have a kind of a roadmap to follow for the process. You have one?
