Code Issues Proposed changes

Update VIM DB migration during major release deployment 

During a orchestrated sw-deploy VIM DB will be in-use.  This means that
the original method of migrating it will not work.

This changes the migration to use hardlinks so that the DB will continue
being used without impact to the orchestration process.

TEST PLAN
PASS: AIO-SX software deploy start with major release

TODO:
PASS: AIO-SX sw-deploy-strategy with major release
PASS: AIO-DX software deploy start with major release
PASS: AIO-DX sw-deploy-strategy with major release
