Storage Account Upgrade: LRS to GRS — Conversion Failure During Background Process

Problem description

I am experiencing an issue when trying to upgrade my storage account from Standard_LRS to Standard_GRS. The request was accepted and entered an 'InProgress' state, but later failed during the background conversion process. The account remains operational and still shows Standard_LRS, but I want to successfully complete the upgrade to GRS.

Environment

Storage Account Management in the East US region.

What I've already tried

I reviewed the activity logs and resource health, confirmed that no management locks are in place, and verified that the account property 'isSkuConversionBlocked' is false. I also checked other accounts in the same resource group and region, which are still on Standard_LRS. No alerts or outages were identified during the conversion window.

Current status

I am seeking guidance on understanding the root cause of the conversion failure and steps I can take to successfully upgrade my storage account to GRS.
