  4.      Install 64bit application software
  5.      Setup Hyper-V #2 VM called SQLServer

You can't migrate from SQL Server 2000 directly to 2012 because isn't supported. You need to migrate first to SQL Server 2005 or 2008 (compatibility only goes 2 versions backwards).

But there's no issues migrating from 32 bit to 64 bit since the databases aren't affected by the architecture. That's more about the efficiency on using the resources.

So the below will work ?
 1. Detach from 32bit SQL 2000
 2. Attach to 64bit SQL 2005 or 2008 --> like my links talked about
 3. Detach from 64bit SQL 2005 or 2008
 4. Attach to 64bit SQL 2012

The steps aren't that direct but almost.
Before step 1 and 3 I will recommend you to run the upgrade advisor  (for SQL 2005/8 and 2012 respectively) to check if there are any incompatibilities.
And after step 2 and 4 you will need to set the compatible mode of the database to the version that you migrated to and run the DBCC CHECKDB with the DATA_PURITY option.
DBCC CHECKDB ('<db_name_goes_here>' ) WITH ALL_ERRORMSGS,NO_INFOMSGS, DATA_PURITY

Open in new window

And for last step some people like to also to update the statistics from all tables or even run a full reindex job. This step you can only do it after migrating to SQL Server 2012.
