ALM suggestion with DEV-TEST-PROD Sync

I have made some changes in the model in Dev (it is in Standard Mode)... Created Rev Tag...

My Prod model is Deployed mode with Rev Tag... 

So I will compare and sync Dev (Standard mode) with Prod (Deployed mode)...

 

Now my Test Model is Archived due to space issue...

So to sync, I have to Archive Dev now...

And they sync Prod (Deployed) with Test (Standard)...

And then again archive Test and bring back Dev...

 

Now my question is:

Is the process, I am thinking is right?...

Will Prod model in Deployed mode be able to Sync correctly with the Test Model...

 

After bringing back Dev will it be auto-compatible with Prod?...

Or do I need to perform Compare & Sync again?...

 

Thanks Friends...

You solution will really help me a lot...
