I am planning to upgrade a Resource Manager and DMA both on a VDM.
However, on the support site in the VDM section there is a warning about the upgrade procedure and -files, however I can't find any specific VDM documents or upgrade files. Or it is not clear enough what's intended.
Anyone any experience, tips, hints?
welcome back to the Polycom Community.
The VDM support page => here <= states:
Looking for example at the DMA support page => here <= it shows the release notes for 220.127.116.11.
The above list on page 18 the Upgrade to version 18.104.22.168 of the RealPresence DMA System, Virtual Edition notes.
If you are still unsure please work with your Polycom reseller for further support.

The VDM I am talking about has DMA version 6.0.2_11, so looking at what's available you could say it could use an upgrade...
However, In the exact release notes on that same VDM support page you are talking about the following is stated:
Note: Supported products
Generally, you are encouraged to upgrade your Polycom systems with the latest software
versions. However,existing RealPresence Video DualManager customers:
Must upgrade their RealPresence Resource Manager systems to version 8.2
Must keep their RealPresence DMA systemson version 6.0.2
Must keep their RealPresence Collaboration Server (RMX) systemson version 8.4
Must keep their RealPresence Access Director systems on v4.1
New RealPresence Video DualManager systems will be deployed with these specific software releases
Can you please explain?
The other thing is that our distributor told us to upgrade any component applicable with the appliance edition upgrade files....
Now what should we do.....?
By my experience:
With VDM running on Dell R610 upgrade DMA to ver. 6.0.6 works fine, but upgrade to ver. 6.1.x fails.
Hope this could help.
Is this manadatory to upgrade the infrastructure devices?
Upgrade version only carry the hot fix bugs in older version and new feature introduction
so why the upgradation required?
The VDM platform is bascially running the DMA and RPRM as virtual machines within a hypervisor. Each VM *thinks* it is an applicance running. You would use the upgrade files for the applicance type in order to upgrade the DMA and RPRM. We don't have upgrade files for the software (VMware/MS HyperV) based products anyway. These are delievered in a OVA format.
The reason you should not upgrade the DMA past 6.0.2 is because there are some serious bugs in every version that you could upgrade to. One bug in particular makes the DMA take up all memory resources. Normally this would be ok, except the DMA VM and RPRM VM are on the same host. So bad things start to happen when this occurs. There are various other bugs and stability issues present in other verions of DMA as well.
Engineering is working on developing a DMA build which you can upgrade to the latest GA. There are some other roadblocks relating to a full suite of testing that needs to happen, but you can expect this software soon. I have a few customers waiting for this so they can start using the RealConnect feature for Lync which requires DMA 6.1+....
So the recommendation is you can upgrade the RPRM to 8.2, but don't touch the DMA. The versions you have listed in your previous post is the versions that were all tested together. as long as you run those versions, you should not experience any difficulities. If you deviate from the versions, then you may experience some issues as this was not previously tested.
The resons you mentioned in trail comment is particular fpr VDM or it is apply on DMA VM platform or hardware based system?
