OK, you're merging. Yay!
You must back up your goals to a text file or be prepared to recreate them. As with all merges, there are lots of folks with grand plans to keep their goals without having to copy-n-paste them. Sorry. It's not going to work. You have one option. Copy-n-paste your goals out into a separate document. That's it.
Can't you just keep the old server name? No. Though the client is OK with it, the bot isn't. Also, the goals are saved in a directory with the server name in it but it's also saved in a file with the city ID. The city ID will change. INVALID PLAN.
Can't I just use the Director to make a backup and restore the backup? No. The city ID is changing. You'd be restoring with the old city IDs. The Director can't know old city ID 123 is new city ID 444. INVALID PLAN.
Can't I just keep the bot running while the merge happens? Nope. I don't even know how to explain the myriad ways this won't help. INVALID PLAN.
So what can I do? Your only option.... The only thing that will work.... Copy-n-paste your goals out of the bot into a file somewhere. Paste them back in when you log in after the merger. That's the only thing that will work. VALID PLAN!
Battle on, warriors.
