we've got about 20Tb of data in 15 vfilers to migrate.
I'd like to know how I can optimize throughput (eg will paring down the snapshots on the source before migrating help?)
How can I best monitor the progress?
I used "snapmirror status" on the last one, it was confusing because while the rate did not seem steady and it progressed up to 150Gb on a volume that was 85/500Gb full then completed.
The main goal is to be able to estimate snapmirror initialization completion ETA so I can plan when I'll be doing the manual cutovers - I need to be watching all the clients during cutover, so can't let it happen automatically in the middle of the night...
Is there a better progress monitor than snapmirror status?

I'm trying the tool - its listing -6% progress for my vFiler migration volume
However it shows other regularly scheduled snapmirrors happening with positive numbers and progress bars
The vfiler volume is > 2Tb
And I keep getting a popup at refresh saying:
"In order to use this version of Snapmirror Progress Monitor you need data ONTAP version 7.3 or higher"
I have 7.3.3
this would be useful!

The negative number could be because of the volume size being more than 2TB and the int declaration in the tool might be 32 bit.
Thanks for the volume size hint. Will check with the tool and get back to you.
With respect to the popup you are getting, can you get the version command output from your filer and the screenshot of the popup so that
we can replicate it inhouse to see whats happening ?

What was the version of the tool that you used ?
That will help in narrowing the problem.
I think for the popup message, you used version 2.1 which give the choice of HTTP/HTTPs to connect to the storage system.
Is the following options enabled on your source storage system ?
options httpd.admin.enable on
options httpd.admin.ssl.enable on
