Subiekt GT - Best Method for Transferring Entire Database to a New Computer

Hello, I have a Subiekt GT with the entire database on one computer, which is already very old. It's time to buy a new one, and now you need to transfer the entire shop assistant to this new computer. Do I have in this case:

1) Make a backup using the "Data transfer" program, then install the sales representative on a new computer and then restore the data?
2) Make a backup using the "Archiver" program, then install the shop assistant on a new computer and then restore the data?

I don't know which option is more suitable for me. Please help.

When you leave the GT you do backup, you record it on pendrive. You install GT on the second computer and with the archiver you unpack the archive from the pendrive. If you created a database on a new installation, you are overwriting it.
It worked for me
During the new installation, I set up a database with the same company data as it was in the old one, while unpacking the archive it wrote to me something like: "A database with this name already exists, update and replace with new data" or something like that.
I replaced and it works from the first kick ...
