As of the time of writing, cross-subscription restore is not supported in Azure Synapse. However, there have been various requests submitted for this particular feature, hence the Synapse team might consider this request for the next release cycle.
In the future, whenever this feature becomes available in Azure Synapse, we will capture it in the book.
With this, we have learned everything about the backup and restoration of Azure Synapse dedicated SQL pools, along with their limitations and usages.
