Changing categories structure : what to do?
We have to :
1 - create new categories
2 - delete or update old ones
3 - move some products under other categories (change the category they belong to)
NOTE : all the products will keep using the same ID. Our MSU htaccess is 644
The first question is : does MSU safely and automatically manages situations 1, 2 and 3? (I have seen the claim of "safe change", but just to be sure I interpretated it correctly)
The second question is : what do I need to check in my installation and architecture to be sure things will happen as expected?
In advance, thanks for your help
