Hi,
I would like to setup a Blue/Green deployment for CF2018.
We are currently using IIS+CF on the same VM and in a separate VM we have the MSSQL instance.

We would like to move to this other architecture in order to be able to perform Blue/Green Zero downtime deployments (see below)
 
Solution we want to implement for Blue/Green

According to CF Administrator, Redis external session storage can only be enabled if J2EE sessions are disabled.

We do use J2EE because of the improved security they offer and we are not planning on giving that up.
 
Is there a way to have the session storage to also manage the J2EE sessions?
Is there any workaround that I might be missing to be able to implement this solution?
How can we keep J2EE sessions replicated in those 2 servers so that we can change traffic requests to one or the other without affecting users?
 
Thanks
