I run XCP Analytics before data migration.
I think that "the number of Atime / ModTime / CreateTime files per period" is a little useful for estimating the capacity of differential synchronization and final synchronization, but for other data, divide the source at the time of data migration.
I don't think it's useful in terms of getting data for the purpose of getting it.
Which data is useful for scan data when designing a migration?
