Issue downscaling redis cache

Question

We want to downscale a Redis Cache from c2 to c1 but it's not doing it. It's says started and accepted, but no downscaling. Tried it twice already. Redis version is 6. And memory is below limits of the downscale option.

Martijn van Halen Thank you for reaching out and sorry about the issue you are facing.

Are you getting any error message that explain why the operation is not completing successfully.? Detailed error messages can help pinpoint the exact cause of the issue.

Sometimes active connections or operations can interfere with scaling operations.

Could you please try the following:

Restarting the Redis Cache before attempting the downscale**.** Restarting can sometimes resolve issues related to stuck operations.

Please verify that all prerequisites and conditions for downscaling are met according to the Azure documentation.
