This thread just got revived because of some weird response, which apparently has been deleted.
As for going live, I've just done this.
This has been a rough ride, not because of AbanteCart but because of all sorts of external factors. The OLD store has crashed entirely, and I've had customers frustrated because they can't order. Meanwhile I've been hard at work trying to get the new store going, in my spare time which is at a premium because my workload has been all-time record. Fortunately I can still go to the old store to copy and paste products, but it's still a LONG process!
I'm still not finished, but went live with the high hopes everything works. I think we're fine. There's still a LOT to do, but priority one is getting up and running. I'm getting there but still have lots of questions, which i will be asking over time.
The VERY good news is that I've received outstanding support here, and the software itself is much easier to navigate and use -- this is BIG, when I need to get the job done. Can't waste time trying to figure out how to do everything. Many thanks!
