WAE not optimizing any traffic after 4.1.7 upgrade

I was running 4.1.5c in my WAAS environment.  I have a 612 as CM, several 512 for remote site WAEs and a 574 at a remote site.  Last  night I updated my CM to 4.1.7 and reloaded.  Management to the CM was reestablished and was able to pull info. and manage WAEs.  I then proceeded to upgrade one of my remote sites to 4.1.7.  After successful upgrade and reload, the WAE will not optimize any traffic.  It's been 16+ hours since upgrade.  Since then, I've deregistered WAE and registered back successfully.  I've reload once more but no success.  Accelerator services are running as expected.  License "enterprise" is activated.  WCCP is redirecting packets as normal from the router.  Nothing has changed environmentally during the upgrade.  I literally expected to upgrade this site to 4.1.7 code, restart the WAE and business would be back to normal.

Are there any caveats to running a 4.1.7 WAE mixed with other 4.1.5c sites?  It looks as if WAE isn't building a topology with the other locations or discovering WAE at destination end though Connection Statistics indicate PT in Progress for flows.

Does anyone have any suggestions or has seen this before?  I haven't had much success researching this exact scenario.  Thanks!

Re: WAE not optimizing any traffic after 4.1.7 upgrade

I haven't been able to work on this since I posted question but started back on issue yesterday.  Couldn't find anything related to issue and nobody replied to this thread so apparently it was more of an issue than the experts here have seen.  So after more investigation I noticed the WCCP flow stats all were zero.  Didn't notice that before because I don't have a lot of experience with the WAAS environment so I'm learning some of the information the WAE CLI can provide to help t-shoot.  WCCP redirection was working and packet statistics for WCCP could be observed as being redirected to and from WAE.  I found an incompatibility with WCCP between router and WAE.  Had to update router IOS. After update, traffic optimization began immediately.  HTTP and CIFS tested well.

So with 4.1.7 upgrade, be prepared for the possibility of an IOS upgrade.  I didn't see any reference to this in the release notes for 4.1.7 image.
