Do I Have to Wait for Initial Change Enumeration to End Before I Can Add a Server Endpoint to a Storage Sync Service Sync Group ?

Question

So, I have just used Azure Data Box to import 14 million files / 10TB from an on-prem file server to Azure Files. This has created a file share in Azure using the transaction optimised tier. I have added this share to a new Storage Sync Service and corresponding Sync Group. All the underlying config for storage account, resource group, networking, etc., are working. I want to add the on-prem server volume to this Sync Group so that they synchronise between the cloud and on-prem copy. However, when I try to add the server endpoint I can't, as the drop-down list is blank and cloud tiering shows as disabled (see image 1/4 and 2/4 attached). Is this perhaps because initial change enumeration on the Azure file share, which began when I created the Sync Group and added the file share, is still ongoing and needs to complete first ?

I did this all before using a small test share and the same on-prem endpoint server and didn't notice this happening, but maybe the initial change enumeration was instantaneous, with the share being small.

@Paul Anderson Firstly, Apologies for the delay response here!

Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

Yes, you are correct. The initial change enumeration process needs to complete before you can add the server endpoint to the sync group. During the initial change enumeration process, Azure File Sync scans the Azure file share to identify all the files and folders that need to be synchronized with the server endpoint. This process can take some time, depending on the number of files and folders in the share.

You can check the status of the initial change enumeration process by going to the Azure portal and selecting the Storage Sync Service that you created. Then, select the Sync Group that you created and click on the "Cloud endpoints" tab. You should see the Azure file share that you added to the sync group. If the initial change enumeration process is still ongoing, you will see a message that says "Initial sync pending" next to the Azure file share

Once the initial change enumeration process is complete, you should be able to add the server endpoint to the sync group. To do this, go to the "Server endpoints" tab in the Sync Group and click on the "Add server endpoint" button. Select the server that you want to add and follow the prompts to complete the process.
