[turba] Upgrading horde and turba. Database problem

[Arminas]

Hi,

I am upgrading horde imp turba and ingo from:
HORDE 2.2.9
IMP 3.2.8
TURBA 1.2.5
to ->
horde 3.2
imp 4.2
turba 2.2
ingo 1.2

But I got a couple of problems with users address books. In elder
version of horde (2.2.9) address books was kept also in turba_objects
table, but under owner_id colum owner was kept in such format:
login at example.com . In the newest version of turba owner is saved as
"login" only without @example.com and etc.. Also, when I'm clicking on
address book to preview error "DB error: no such table " is shown. But
turba_objects table exists. So there is my questions:
1. How to remove not nessesary strings in owner_id column "@example.com"
2. What other steps are needed to complete upgrade?

Thanks for reading my post :)
