I am sorry if this has been answered i could not find it or missed it

I have this on a site it's amazing it was all new and only 70 skus.

However I want to add it to another site and it has 5,000 SKU's. Needless to say I don't want to manually open each one and save it thus generating the new address.

PLUS I don't want to lose the settings as the db is updated using ezpopulate and those updates are frequent.

Am I missing something or is there add on software to automate this process because I am scared to even start that one.
