MarkLogic migration

Question

I have a MarkLogic server on an ec2 linux 7. I want to migrate it to a linux 6. I moved the ebs to the new linux 6 and mounted it on /var/opt/MarkLogic.

I am able to start MarkLogic and access the admin page using web. All looked great until I started getting errors today. I am new to MarkLogic.

Looks like in your moving data around you've corrupted your on-disk configuration setup and/or data so now it has an empty string database id, which is choking some admin code which doesn't expect that to ever be able to happen. It's not a code issue, it's that the configuration data on disk isn't entirely consistent. Maybe you moved some data but not all. Maybe you did all this data moving while the server was running. I can't tell from here.

You say you're new to MarkLogic, so this is probably just a dev server, so my advice would be to simply start fresh.
