Hi Olivier,
We have used (succesfully) the migration tool to prepare J2Store for upgrade to Joomla 4 and later 5.
In the phpMyAdmin database we notice several tables starting with V2_j2store. Are these still in use for the present version, or can they be deleted?
Kind regards, Paul Vos
Hello Paul,
the table names have not changed and no table has been replaced from the last Joomla 3 version.
If the tables prefix is v2_ for all tables as well, then you need to keep them.
For instance, on one of my test sites, I have tables
derss_history
derss_j2store_addresses
...
derss_ is my table prefix and can be different from yours.
You have to check what is your site's prefix.
Go to the global configuration and check the 'Database Tables Prefix' parameter. If it is something other than v2_ then you probably do not use the tables starting with v2_ any longer.
If your j2store tables are more like:
derss_history
derss_V2_j2store_addresses
Then these have not been created with j2store and may be copies and are not used.
But in this use case, make sure you still have
derss_j2store_addresses
