Need suggestion on upgrade strategy

We have an aplication on PRPC 6.3 with CPM for FS framework running in production. There are some CR's approved and available in UAT ready to be moved to production soon and few CR's yet to be approved. Also there are fixes for some bug's in UAT yet to be moved to production.

With this state of the application (Code in pre-production is more than production with 12 CR's and some Bug fixes) we are thinking through what would be the better approach for Pega 7 Upgrade.

Approach 1: Take the production CUT as of today and upgrade to Pega 7. Install the approved CR's and Bug Fixes once the upgrade is successful and retrofit these rules based on need.

Approach 2: Upgrade along with all the CR's and Bug Fixes to Pega 7 and later delete the ruleset versions pertaining to the specific CR's which are not approved by the customer for production (In this case ruleset skimming will not be done before upgrade)

Approach 3: Skim the production CUT to one version and install all the CR's and bug fixes on top of the skimmed version before upgrade. Perform Pega 7 upgrade and delete the unwanted RS versions if any specific CR is not approved.

These three options have been thought through but we are looking at understanding what would the best approach which can result in maxium gain in terms of time, effort and risk. Please let us know your recommendations and any other alternative way out other than the three options above.
