Access to old Blue after switch (AMS)

[#1]

Request for Feature Enhancement (RFE) Summary:	Need access to old Blue environment after Blue/Green switch
Use-case:	To evaluate roll-back decision based on the issues found after Blue/Green switch we need to be able to verify issue is introduced due to the change, or existing issue.
Current/Experienced Behavior:	Currently, old Blue environment is only accessible by Adobe, and not integrated with the rest of the systems.
Improved/Expected Behavior:	Instead of putting the old Blue environment away, place them into the Green Load-Balancer, so that Green URL can be used after the switch.
Environment Details (AEM version/service pack, any other specifics if applicable):	Cloud Manager for AMS deployment
Customer-name/Organization name:	Go Endo

Hi @Jyin 
I think, If blue environment is not deleted, then it is possible to access blue environment after switch.

we also have blue/green setup and we always access both using live and preview load balancers.

Here Adobe CSE can help to setup 2 different load balancer and allow you to access blue environment over preview load balancer.
