Can I use TestTrack native databases on the 64-bit TestTrack Server?
Yes. TestTrack 2012 or later native databases are supported. If you want to migrate from a TestTrack 2011.1 or earlier native database to the 64-bit server, you must upgrade old native databases to the current version before installing the 64-bit server. See Migrating from the 32-bit TestTrack Server to the 64-bit TestTrack Server on the Same Computer for information.
