Migrate ServiceDesk Plus to another server

Migrate ServiceDesk Plus to another server

Hello everyone, 
I have to migrate SD from 32bits to 64 bits, so Im trying to do it to a second server, because I cant get stopped the productive server so much time.
The server prod is still running, and I installed the app at 64 bits on a new server.
I've taken a backup from the server prod, then moved to the new one, and when I try to restore I get an error:
Restoring... |
Problem while restoring db
Reading the logs, I found this: "R0RP1 incompatible backup file"

Whats the correct process to migrate to another server?

Data:
db is postgresql
old server is version 32bits 13.0 build 13007
new server is version 64bits 13.0 build 13007, postgresql too.

Thanks so much!
