I've done a JUPGRADE on a 1.5 site to 2.5 - did all the necessary debugging on CB Subs, DT Register and JEvents, etc. to bring everything current (and using the DB from the old 1.5 site.) The old site is still active for a few months and (paid) user membership on the old site has continued while the new site is being built.

I'm ready to import the current 1.5 user DB to the new site to go live. Does anyone have any advice on best practices to do this? I've backed everything up, BTW.

Is CB Juice the best answer and will it just overwrite the current users? Will going from 1.5 to 2.5 be an issue if tables etc. have changed or does CB Juice handle all that?

I'm just trying to get any information that might be of value. I'm happy to read any tech article or tutorial, etc. if someone will point me to it.

Thanks in advance,
Mark
