Host DAG nodes in Azure

Due to a forced closure of one of my data centers I'm having to look for alternative solutions for my 2016 Exchange DAG that currently spans two DC's. This change is being managed under a very tight deadline (5 months) and hence, limited options are available.

One option being explored is to place the data center in Azure IaaS and to configure WAN connectivity between Azure and our corporate network. So my question here is:- Does Microsoft suppport the deployment of Exchange 2016 running in Azure configured with premium storage? Further more, subject of course to the right network connections, will my current Exchange 2016 DAG continue to function running in Azure IaaS.

I've heard it said that while Exchange 2013 and above are supported, VM's requiring multiple virtual nics are not supported and that limited support is provided for the DAG fail-over feature.

What is & isn't supported and what are the likely issues we could encounter pls

    Yep, that is supported as long as you meet all the same requirements that would need to build an on-prem solution.

    Not sure what you mean howver by "that limited support is provided for the DAG fail-over feature."

    If you can provide any documentation, otherwise, I would go by this doc which says its supported

    and this one:
