The storage is also fc on both versions.
Checked if there is any issues in network also gone through firewall settings and found no issues.
This is usually not feasible but can be preferred if the migration project is time critical.
Now your mailboxes will move without any throttling policy.
But status shows syncing.
When i initially issued the moved requests the migrations were running about 10mbps and only moving about 5 mailboxes at a time.
Today while migrating mailboxes from exchange 2010 to exchange 2013 it s very slow.
Analysis of the move request shows that the sourcesideduration value is greater than the expected range of 60 to 80 percent.
Delete empty mailbox folders or consolidate mailbox folders.
I also can tell you i saw more errors and stalled out mailboxes moves than i have ever seen in any migration or even in any number of migrations combined while trying to perform these moves.
Mailbox migration exchange 2010 to exchange 2016.
The mailbox size was 5 5gb and it took around 2 hours and 50 minutes to complete.
You can use the exchange admin center or exchange online powershell to migrate the contents of users mailboxes from an imap messaging system to their microsoft 365 or office 365 mailboxes.
Hi i installed exchange 2016 on vmware exchange is working good when i start the user mailbox move from exchange 2016 user mailbox moving issues very slow i have 400 account now i think what should i do for the fast moving because if i started all mailbox moving i think the issue will be have.

I recently built new exchange 2016 servers for a customer and needed to move all of the users mailboxes to the new servers.
Hybrid mailbox migration for one or more large mailboxes is slow because of network latency.
Migrate mailboxes from servers closer to office 365 datacenters.
High network latency affects the move rate more if there are too many folders.
Hi try the following settings and see how it goes.
Once the mailbox migration is complete change the value back to 1 to re enable mrs resource monitoring.
Try one or a combination of these in your environment and see what works best for you.
Then restart the exchange mailbox replication service.
This includes migrating your mailboxes from other hosted email services such as gmail or yahoo mail.
The servers have 128gb ram and 16 core cpu.
Needless to say if your migration is going on at a frequency that is less than the figures mentioned above your exchange 2013 migration is actually running slow.
Today this blog will show the enhanced migration procedure.
