Change application server from Websphere to Tomcat
I would like to study the possibility of downsizing my Pega7's application server from websphere application server 8.5 to apache tomcat 8.5 . I have some questions in my mind:
1. Does Pega7 formally support running tomcat in production environment?
2. If I move to tomcat, can Pega7 still provide same functionalities (such as session replication, async task and message bean) as Websphere application server?
3. Any documentation/guideline for moving Pega7 from Websphere to Tomcat?
