Description
I have an existing event store and lease documents; and I'm looking to migrate them to a new CosmosDB. What I'm seeing in my research is the existing `id` field on my lease documents will no longer match in the new database due to the [host, database, and collection resource ID changing](https://github.com/Azure/azure-documentdb-changefeedprocessor-dotnet/blob/master/src/DocumentDB.ChangeFeedProcessor/ChangeFeedProcessorBuilder.cs#L521-L523).
Is there a known way to cold-migrate the documents to a new database while maintaining the previous `ContinuationToken`?
