Re: Compatibility between server 6.5 and client 6.0 Greetings, All server code is QAed with previous versions of Integrity Client. This means that 6.0 clients are successfully tested with 6.5 server before going GA. It does not work the other way. 6.5 clients are not tested with 6.0 server. So you can run both clients with 6.5 server. This does not work with 5.x clients they use a different hb port. When you upgrade it may be wise to export your corp connected policy and deploy it as the disconnected policy. Reason: During the upgrade your IAS server will be done and clients will activate the disconnected/personal policy. I suppose you could also check enable corp policy all the time. Be sure to examine the Readme file sent with the Installation of 6.5 it warns about a conf file that does not retain settings when upgrading from 6.0. I have seen this occur even within 6.5 HFA upgrades in certain circumstances. YOu will have additional considerations if you are also migrating to a new IP, DNS host name, or if you doing HA. IN a cluster you would upgrade you master memeber and test. Following a successful test then do a new install & join for the rest of the member servers. hth |
