Upgrade in my shop is a dangerous thing here because I have installed the master card, visa, and a bunch of other adds-on what they do and make migration difficult. According to the administrator of my site it says it can not "reclaim" the database - especially on the part of customers and orders. I have 3500 registered customers and sooner or later I'll have to take action ... This day will be fire, but I'm still trying to work with the tools I have.
Thanks for now, Andres
I used realy 2.2ms2 version -
