Long time ago we had old server called wm-bot, then we had to reimage it and labs don't support renames, so wm-bot2 was created and wm-bot deleted.
Now we needed upgrade from debian 8 to debian 9 so new server wm-bot was created. Nothing is running there though
[x] setup .net core runtime
[ ] figure out if we can get instance with more storage, this is not enough
[ ] check if postgres and mysql connection works fine
[ ] check if all network ports we need to use are properly configured
[ ] check all locations - are html pages, and logs on shared storage? do we need to copy them?
[ ] announce the migration somehow - bot will be down for hours
[ ] shutdown wm-bot on wm-bot2
[ ] transfer all configuration from wm-bot2
[ ] copy logs if needed
[ ] start wm-bot on wm-bot
[ ] delete old instance
