restoring redshift serverless from provisioned cluster snapshot

Question

I recently enabled redshift serverless endpoint, and to benchmark it I want to restore it from a snapshot of a legacy provisioned cluster, so we have identical data sets to start with.
However, when I select to restore the snapshot to the serverless (using console as described in https://docs.aws.amazon.com/redshift/latest/mgmt/serverless-snapshots-recovery.html, and confirming that it will replace all my serverless databases), nothing seems to happen (no error, but also the serverless databases are not replaced with the snapshot).

I already tried adding redshift full access policy to the IAM role of the serverless endpoint, but that didn't help.

Has anyone already achieved this?

Answer

Kindly review that either the administrator permission 
```
arn:aws:iam::aws:policy/AdministratorAccess
```
 or the full Amazon Redshift permission 
```
arn:aws:iam::aws:policy/AmazonRedshiftFullAccess
```
 is attached to the IAM policy that you used. If true, then open a Support Ticket for assistance.
