the reason we have not upgraded our BC stores to the latest release.
It adds lots more work to what was a simple task.
My main actinic site is going to ISC which about 900 products, most of these products have unique options, but they are easy to set up and can be seen on one page so easy to change if need be.
I have a test site on BC running which I converted all old variations to new options, it makes one hell of a mess and not something you could leave in the hands of a junior.
Yep leave it alone for a while til they sort it all out - ties in with a recent thread on here about not being a crash test dummy. Ive not upgraded any of my BC sites
