Hello Rishabh Srivastava,
Thank you for posting your query here!
In order to migrate an Azure storage account from LRS to ZRS replication, you can Perform a conversion.
There are two ways to initiate a conversion:
• Customer-initiated
• Support-initiated
Customer-initiated conversion:
Now you can initiate the migration yourself. Select the storage account you want to migrate and navigate into the Redundancy section.
A confirmation is needed, and the storage account gets submitted for conversion. The migration is started within 72 hours and can take several days for large storage accounts.
You can achieve the same using PowerShell/CLI, for details please refer: https://learn.microsoft.com/en-us/azure/storage/common/redundancy-migration?WT.mc_id=AZ-MVP-5000119&tabs=powershell#customer-initiated-conversion
Or else you can still request a conversion by opening a support request with Microsoft i.e., Support-initiated.
For details on the same: https://learn.microsoft.com/en-us/azure/storage/common/redundancy-migration?WT.mc_id=AZ-MVP-5000119&tabs=portal#support-initiated-conversion
