Avoid VR downtime when upgrading ACS
Dear all,
I have done some extensive tests on upgrading ACS from 4.2 to 4.8, and one
of the steps involves upgrading the virtual routers (VRs) which will cause
downtime to network served by the VRs. Is there a way I can avoid such
downtime?
Will having redundant VRs for every network help to avoid the downtime?
Looking forward to your reply, thank youi.
Cheers.

Is I recall correctly, there is an old PR sitting out there to address this.

I would be inclined to say it is not possible to avoid a little bit of
downtime (at least not with we have today in ACS). People have worked to
reduce the downtime (starting at 4.8 or 4.9, I do not recall the precise
version right now), but I think we have not achieved a stage that we
successfully eliminated it.

Using redundant VRs can solve your issue but right now that functionality
is broken [1] This will be fixed in 4.10.

Hi,
Sorry to bring up an old question, just want to ask again if anyone knows
if we can upgrade ACS and avoid the downtime caused when the VRs are being
upgraded?
Looking forward to your reply, thank you.
Cheers.
