New SnapMirror baseline transfers needed?

Hi guys,

 

assuming the following scenario:

 

I fully replicated 2 volumes from on-prem FAS (ONTAP 9.1) to AWS Cloud.

1 volume from on-prem FAS to ONTAP Cloud on AWS and

1 volume from on-prem FAS to AltaVault on AWS.

Now I want to switch from AWS to Azure.

 

Can I do this:

a) Deploy a new ONTAP Cloud & AltaVault appliance on Azure

b) Break the current on-prem to AWS SM relationships

c) SnapMirror the volumes which are already residing on AWS to Azure and once completed, break those SM relationships

d) Establish new SM relationships from on-prem to Azure and sync deltas

 

 

Will the steps above work or do I need new baseline transfers from on-prem to Azure??

 

 

In case a new baseline is needed, is there already development in avoiding that in the future?

 

 

Thanks!

Re: New SnapMirror baseline transfers needed?

Responses are inline:

 

 

a) Deploy a new ONTAP Cloud & AltaVault appliance on Azure

AltaVault can be deployed on Azure as an AVA-c4 only (no support for AVA-c8 or AVA-c16). ONTAP cloud support for Azure is also limited if I remember correctly (vs. AWS).

 

b) Break the current on-prem to AWS SM relationships

Are you breaking both relationships (I assume yes?)

 

c) SnapMirror the volumes which are already residing on AWS to Azure and once completed, break those SM relationships

That seems reasonable, assuming the ONTAP cloud version can support it.

 

d) Establish new SM relationships from on-prem to Azure and sync deltas

Yes, that should work too (resync)

  

e) Will the steps above work or do I need new baseline transfers from on-prem to Azure??

You shouldn't need to do a new baseline is my understanding.

 

 

f) In case a new baseline is needed, is there already development in avoiding that in the future?

Not that I'm aware of.

 

I'm going to loop in another ONTAP cloud resource to ensure my responses are correct for the above. He'll respond separately if I can get him engaged.
