I have a model that I would like to create a production model from. Currently, the model is in the target workspace, not in our development workspace. In order to not break sync, would it be better to move the current model into the development workspace then create a production copy?
You can copy model into the target workspace itself by clicking on "Create Model from Revision" and then import the model into other workspaces. Importing the model doesn't break the sync. This option will just create the model without production data and you can use this model as Dev model for your existing model
On the other hand Copy model copies the model along with production data and creates a revision tag in the source model and copied target model.
I have already set up my production lists and production imports. If I'm understanding you correctly, you suggest copying the model and importing the copy into the Dev workspace? Then I would just change the original model to be in production?
This is correct. Once you copy a model, both are compatible until you start making changes. Copy the model into a new workspace, make the original (Production) Deployed, and then make all your changes in your new DEV and ALM will work just fine.
One-piece to note is that your model history will not copy, so your previous development work's history will remain in your production model as opposed to moving with your DEV model.
Ultimately it depends what you want to happen with the data.
If you copy the model using the import function, then it will retain data that is typed into cells. If this is what my current model looked like, the copy would be identical:
If you use the Create from revision tag feature, the data will not carry over and this is what the same module would look like:
So either will work, but you need to decide if you want to copy your data as well or not. If you use the create from revision tag feature, be sure to create a new revision tag before creating the new model so you dont lose any work form the last revision tag until now.
Let me know if there is something that is unclear!
