Hello,

I don't want to spend nights to try to upgrade from the 1.2.2 to the last.
Could I then just import the database into a fresh new zenphoto gallery and use my old /albums/

thank you

Your best bet would be to do a bit of reading: http://www.zenphoto.org/news/installation-and-upgrading#2.

Then mayabe post your question only once!
