Any experience in the migration of 500GB in 50.000 PublicFolders to Modern PF ?

Source is Ex2010Sp3 latest RU.

How long does it take?

I did a migration for a customer a couple of months ago.

Customer had 5000 Public folders, with a total data size of 950gb.

initial sync took around 12 hours to complete with batch migration.

Finalization took around 1 hour to complete. All PF servers was in same site.

Was migrating from Ex2010 to Ex2013 with the latest RU/CU at the time of the migration.

Be sure to check logs before completing migration, and fix the errors you probably will encounter.
