Unzip your Back up File, And in each dump.sql file, You will have some things saying " %%TBL-PREFIX%% ". Change that text into " ow_ " and then import the files into the MySQL Database using PhpMyAdmin.
"BACKUP SITE"
you simply use Notepad + + to search for that keyword and replace it.
Notepad + + can replace these keywords are all within 1 minute
but the thing to remember I did not succeed in importing the user, through this way. This will serve to move the Blogs, Links, Messages, Status and Events
you can try but you have to back up first
Step by Step:
PhpMyAdmin => Import => Import dump.sql => done
I succeeded, move the blog, links and others unless the user ..
you have to go into phpadmin and upload one by one.
This all should work.
I tried it and it worked, but I did not try to move users
