Moving a stroage account between subscriptions

Umer Ahmed 20

Hello Support,

I'm planning to move a Storage account that has a container with 10TB of data. This SA is integrl to our CICD system, hence we can't afford a downtime. So, i'm a bit cautious with this move and have the following questions:

how long this move would take?
what happens if the move fails?
will there be a downtime during the move operation?

please let me know

thanks

Umer

If high availability is crucial, convert the storage account to zone-redundant storage (ZRS) within the primary region.

ZRS replicates data across three separate data centers using Azure availability zones.

Hello Karishma,

thanks for your message, I wanted to ask what benefit would this give me in the context of this move? Its currently set to LRS, which gurantees this:
Locally redundant storage (LRS) replicates your storage account three times within a single data center in the primary region. LRS provides at least 99.999999999% (11 nines) durability of objects over a given year.

So its replicated already, i don't think replicating it across regions is going to bring any more benefit in this context. Can you please answer the questions i've asked, most importantly:

what happens if the move fails?

as I need to have a roll back plan

As per https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/move-resource-group-and-subscription , the content of the storage account (data plane) will be accessible during the migration. The management of the storage account (control plane) will be locked (unavailable) for a maximum of four hours, but most moves complete in much less time.

If the move fails, the storage account will remain in place.
