I’ve been putting off upgrading to 2.x because the upgrade terrifies me. I attempted to do it around the first of the year and my site was down for three days. We did a complete restore to 1.x version from backups, which left the site still at 1.x.
Today it occurred to me that I might be able to leave the 1.x install alone and do a separate 2.x install in a different folder on the same site. Can that be done without major problems? If possible, can I copy the membership table from the 1.x install to the 2.x install so the members have access to the new install? By the way, I would disable login and registration on the 1.x install.
Is this a crazy idea?
