PVS 1912 LTSR downgrade compability

[Thorsten Hanke-Gyssling]

Hello

after upgrade our infrastricture to PVS 1912 ltsr we have many problems with our citrix servers since the freeze during the day.
we have tested and changed network card settings but nothing helps, so one last step is to install for test 2 new pvs servers with old version.

 

is it possible to yes the vdisk with the new target device software but connected to the old 7.15 pvs servers?

 

Regards
Thorsten

I assume you have already upgraded the target device software on the targets to 1912 so would have 1912 target devices connecting to a 7.15 PVS Server. Even if it works it doesn't seem you would want to run that way for very long.

Hi @Thorsten Hanke-Gyssling

 

We are also running 1912 PVS, everything on Windows Server 2019 Datacenter VMs, and our VDAs are randomly experiencing server freezes where we have to do a hard reboot to get it running again.  When you downgraded your network cards to E1000, did you do that on the PVS servers, Deliver Controller servers, target VDA servers, or all of them?

Hi

we only downgraded the VMs to E1000 network cards and all seams fine in the moment.

Hi @Thorsten Hanke-Gyssling

 

Did you only downgrade the VDA VMs, or also the PVS and Delivery Controller VMs?  Also, did you notice any performance impact after downgrading, or an increase in CPU usage with the E1000 cards?

 

Thanks

Hi

we only changed the network cards on the VMs.

in the moment we didnt explain any performance issues or anything.
