I'm in the process of re-aligning our properties files between our production and testbed servers which are/were initially setup identically.  I'm doing this in preparation for upgrading to 6x, doing our testbed first then production if all goes well.   In review of the properties files I noted differences between our 2 servers that i could only attribute to the upgrade path taken. Our testbed went from 406 -> 501 -> 502 whereas our prod server when from 406->502 directly.  (The JTS/RM split timeframe).  

In any event  I've re-aligned the properties files and have not noted any issues as a result of this however there are a few deltas that I'm trying to figure out that i hope someone can address as the JTS/RM split was not as clean as it should have been.

One property I'm questioning in each apps teamserver.properties (jts, rm, qm, ccm) is the LPA storage area.
In both JTS and RM under Lifecycle Project Administration Component,
com.ibm.team.lpa.app.services.LifecycleProjectAdminInitService: Storage Area Name
Both JTS and RM have the same value defined e.g. com.ibm.team.lpa.9f335f75-c0dc-4992-8f2f-44c9f61a5a5a
whereas both CCM and QM also have the same attribute defined but are blank.

Should they both have a value same as RM or should RM's value also be blank?

Another one is com.ibm.team.datawarehouse.db.net.port. The port is defined in both JTS and RM. It is also efined in QM but no port is specified. For CCM it is not listed.

Should each app's properties file have this defined? Only in JTS ?
