Currently i have magento setup using multi sites (store views which go to other sites). I have around 7 stores setup in this way all running of a single backend and database. Over time its become very bulky, for instance my database weighs in at over 1GB and indexing is now a very lengthy process. So for obvious reasons i am now splitting these up into there own magento backend / database.
I have managed to do exactly that by duplicating my magento install and deleting the unecessary store views leaving the 1 store i want to keep. The problem of course is magento does not delete the database entries for these deleted stores so i still have a very bulky database with unecessary data.
So my question - How can i delete this left over data in my database ? I assume magento keeps some sort of id's to link the data to the store view so perhaps an sql query exists that i can run.
