Multiple Models in Oracle Configurator

Hi All,

We have a CZ gold Instance,in that there is only model M.We publish that to testing  and production instances.

Now the requirement is for each instance we need different model versioning,as we are going to copy the existing model to different folder M1
which we will use for testing instance.

After successful testing,we are going to copy that model of testing to different folder M2  for production.

Now M for dev,M1 for Testing and M2 for production.

Is it a good idea to do,or do we have any other way to achive that.
