WAAS Upgrade CM path from 4.4.7 WAE-512 to 5.4 vCM

Edward Clear

I have a deployed WAAS system running 4.4.7 and the old WAE hardware is all on the EOL clock or not supporting 5.4 at all.   The budge fairies had money at the end of the year so I've got new WAVE boxes and vCM 5.4 DVDs to deploy.

My question is what is the upgrade process for the CMs?  

Can I simply spin up  two 5.4 vCMs as a secondary CMs to the 4.4.7 primary CM on a WAE-512, then make one the primary?  That would assume that a 5.4 secondary could sync to and then take over directly from a 4.4.7 primary.  That's the bit that I have doubts about.

Or would I have to start with vCMs at 4.4.7 to get them to sync, then take over as primary and upgrade them?  Is there a 4.4.7 vCM image?

If that's a dead end, I saw another discussion about downgrading a WAVE-294.   I'm thinking one could be downgraded to 4.4.7, joined as a secondary CM, promoted to primary, and then upgraded as a stepping stone to vCMs at 5.4.  Then the '294 would be deployed back as accelerator as originally intended.  Any pitfalls with this?

Or is there a simpler path that I'm missing entirely?

Also can anyone confirm that the RJ-45 console ports on the WAVE-*94 have the same pin-out as traditional Cisco switch RJ-45 console ports?

Thanks.

Hi Edward,

 

For the upgrade process, you'll have to follow this procedure :

http://www.cisco.com/c/en/us/td/docs/app_ntwk_services/waas/waas/v541/release/note/waas541xrn.html#pgfId-171257

So either down grade your vCM to 4.4.7 (this requires that it is a vCM-100 or -2000)

- there probably is a vCM 4.4.7 image out there somewhere, but these could be hard to get.

- or just use the "copy ... install" on your vCM, to get it downgraded.

or use the 294 method (same methodology applies)

But as I see it, there is no need to play around wit ha secondary CM, you don't need the CM to ensure optimization, when things are up and running.

You can easily change a CM to an accellerator by configuration and a reload, unless we're taking vWAAS, where the ova image is locked.

 

remember to take a backup of your CMS database and place it somewhere else, before starting upgrading.

Thank you.  For some reason I didn't think about release notes.   So the pieces I were missing is that once the OVA is loaded, it can be downgraded using the same methods as a physical box and to use the DB backup rather than becoming a new secondary.

It was interesting in the release notes that, although they state you need to downgrade the new CM to the same version as the old before importing the DB, the example output from the importation states the DB data is from an older version and will be updated.  I will go for an exact version match though.

Hi Edward,

 

Suggest that you do that (same version).

Problem with much of the examples within the Cisco documentation is that they are made outside the real document, which describes how it should be made.

Figured out the serial RJ-45 pin-out empirically.   Yes, it's the same as on switches.
