I think the problem is that too many people, all with best intentions, gave 
you different advise. On one hand that's awesome because it shows that we have 
a small community on this mailing list who is trying to help each other. On 
the other hand it can be confusing for the person seeking help.

I think that I know pretty well how KMail and Akonadi work. I have migrated my 
local mail in KMail from KDE 2 times until today on my PC. On my laptop I 
chose to do a fresh restart many years ago, but that was rather painless 
because by then I only used a few IMAP accounts with server-side filtering.

On 3 December 2021, David Jarvie wrote how he managed to get KMail use his old 
mail in ~/Mail. This should also work for you to make KMail see the old mail 
store that you restored from the backup. Also, think I already wrote that you 
should try to talk to the IMAP servers directly with the new KMail instead of 
trying to make your old complex setup, that may have served you well with the 
pre-Akonadi KMail, work with the "new" Akonadi-based KMail.

So, my final advise is:
* Ditch your old complex mail setup. (I understand that this may be difficult 
because it has served you well in the past, but I think now it's time to let 
go and give the new (better?) KMail a chance.)
* Have another look at David Jarvie's mail to see how he got his old mail into 
KMail.
* Make KMail talk directly to your IMAP accounts.

Regards,
Ingo
