pt3 database in pt4

[mariusb]

I have a problem, when importing hands in PT4 it stays too long, around 50hands/s, so I tried to import the hands in PT3 and then use the database in PT4. but I don't know how to use the database created in PT3 in PT4. Can you help me please?

PT4 cannot use PT3 databases; the database structure PT4 needs is different than the kind PT3 builds.

One thing you could do is export your PT3 data manually and import it into PT4 in pieces that way you could manage exactly how large each import will be.

I upgraded my workstation, installed PT 4 and now I have only backup-zip from the old PT 3 configuration. Seems to be that there is DB0.backup and DB1.backup files in zip archive. Could I just import those into the same database and therefore try to use Tools -> Setup Assistant -> Import PT 3 ... or is there some proprieraty format in .backup files? Can I just use psql tool for that?

If those are backup files made by PT3 then the easiest thing to do will be to install PT3 and restore the backups - then you can either convert them using PT4 or export the hands from PT3 manually as Kraada suggested.

If you have all of your original hand history files you could import from those directly instead.
