Important

To resubscribe an Edge Transport server, export a new Edge Subscription file on the Edge Transport server and then import the XML file on a Mailbox server. You will need to resubscribe the Edge Transport server to the same Active Directory site where it was originally subscribed. You don't need to first remove the original Edge Subscription; the resubscription process will overwrite the existing Edge Subscription.

Hi @fsdg-2871

Yes, that's the correct way.

You can just follow the official document you shared above or refer to the link below for Exchage 2010:
Understanding Edge Subscriptions

  1. On the Edge Transport server, create and export an Edge Subscription file. For more information about this step, see Create an Edge Subscription File on an Edge Transport Server.

  2. Copy the Edge Subscription file to a Hub Transport server or a file share that's accessible from the Active Directory site that has your Hub Transport servers.

  3. Import the Edge Subscription file to your Active Directory site to which you want to subscribe your Edge Transport server. For more information about this step, see Import an Edge Subscription File to an Active Directory Site.

Do I need to remove old subscription on Edge server or HUB transport server or leave both as it is?

Hi @fsdg-2871,

You can leave both as it is. As cited in your original post, "the resubscription process will overwrite the existing Edge Subscription":
