Re: Moving files in folder - strategy?
Hi nikosal:
If you have the option in the new server to import your db from the command line ( mysql -uuser -p new_db < old_db_dump.sql ), then I would suggesst that you upgrade using your second option ("b").
Otherwise, if you have to import your db through phpmyadmin or similar in the new server, then you have to follow your option "a".
More information on how to move files from db to disk:

Remember that image galleries are deprecated, so sooner or later, you will have to move images in them to file galleries in new Tikis.
