When in the upgrade process should we upgrade the app server ?
We are planning a migration from Pega 6.3 to Pega 7.
Because our current application server, server hardware and java version will not be supported by Pega 7, we will need to upgrade those components as well.
My question is: When in the update process can we upgrade the app server ?
The database will not change so could we for example, run the in-placer or Out-of-place migration on the database only? Then in parallel, upgrade the application server. And do these tasks independently from each other? Are those two tasks totally independant?
We have: Pega 6.3 on Jboss 5.1.2 on an Oracle Linux Server 6.5. (None is supported by Pega 7)
We will upgrade to: Pega 7, Jboss 6.4 on an Oracle linux server 7 (Not supported by Pega 6).
When should we upgrade the app server and server hardware in the overall migration process?
Any advice would be appreciated,

Please see the Upgrade Guide for your target release for more information. For example, the Pega 7.1.9 Platform Upgrade Guide includes this information:
If you are updating the version, or changing the vendor of your database server or application server, complete and verify those changes before upgrading the Pega 7 Platform. If you upgrade the supporting software at the same time as you upgrade the Pega 7 Platform, it is difficult to isolate the cause of any problems that might occur.
