Server Error on Startup after Migration

I migrated my TeamCity server from Windows to Linux.  Steps I took:

1. Installed same version on linux that I had in windows.

2. Copied over the backup of the database.

3. Created a database.properties file based on mysql

4. Ran maintaindb.sh 

5. Copied over system/artifacts from old to new

6. Copied over system/plugindata from old to new

7. Copied over plugins from old to new.

Started server.   Failed, with the following log.

It's the second to last night "[2016-08-28 20:35:01,336] ERROR - jetbrains.buildServer.STARTUP - Found a TeamCity internal database when no system directory or an empty system directory is expected" that has me completely thrown off. Anyone have any ideas?
