Re: [Proposal] new API for recover routers

Hi Rene,

So if you have upgraded 4.5 to 4.11 (or any version upgrade where new system VM templates are in play) then your 4.5 VRs are by definition destroyed and you are running with 4.11 VRs. As a result there is nothing to recover – the rollback mechanism in this case is to roll back DB, destroy all 4.11 VRs (and anything else unknown to the original DB) – then start up the 4.5 management servers. At this point CloudStack management will either automatically build “new” 4.5 VRs – or worst case you do a network restart which recreates the VR.

If you haven’t upgraded the VRs – and they are still running as version 4.5 under a 4.11 management server – then the rollback is a straight forward DB rollback and management restart – the original VRs will stay in place.

    While tested v4.11.1 in the lab and upgraded the routers, we came across
    the need of "downgrade" the routers after rolled back to ACS to v4.5
    (testing upgrade process).
    So my proposal is to have a new api for recover the routers to the
    system-vm template, AFAICS similar to
    but for routers.
    Any thoughts?
