Change from PAYG to BYOL in Azure

[Alan_Long]

We are looking to move from PAYG to BYOL in Azure, Has anyone done this and can share some details of what was done to make the move? We will be also going from R80.30 to R81.10. Need to limit downtime as much as possible during this process. Thanks.

Unfortunately this cannot be achieved in-place and the CG instances will need to be redeployed.

Namely a parallel build and migration of traffic by updating UDRs and similar I expect.

Specifics will depend on your topology and current deployment e.g. VMSS vs HA etc

Thanks Chris,

Let me ask this. We built the clusters as payg, they are ha clusters. Can we take down one member of the cluster, rebuild it as byol, put it back in the cluster, then fail to it, and do same with other member? Or do we have to drop the whole cluster, and start from scratch?

PAYG and BYOL licenses are different and different licenses on different cluster members is not supported.
You will need to rebuild the cluster.
