title: Speed and Impact of Azure SQL Geo-Replication Sync
body: <p>I have a client who's Azure SQL database was accidentally created in a European datacenter (the client is in the US). I was hoping to move it to the US using Geo-Replication to minimize downtime as outlined here:

  <p>The database is moderately large at around 25GB and I can't seem to find anything on the following questions:</p>
  
  <p>1) Is there anyway to gauge how long the initial sync will take (ie. all data is synced and we can failover to the new DB in the US)?
  2) Is there anyway to view the progress of the initial sync?
  3) Will the performance of the database be substantially impacted by the initial sync (and subsequent synchronization)?
  4) Will bumping the server tier up improve any of these outcomes (ie. speed of sync and performance impact)?</p>
