Can OMS Only Migrate the Data Generated After a Specified Time?

OMS allows you to filter data to be migrated by time using the Selective Migration option.

• If you do not need to filter source data by time, set this option to No.
• If you need to filter source data by time, set this option to Yes. Then only source data modified after the specified time will be migrated.
  

  The specified time cannot be later than the start time of the migration task. Otherwise, no data will be migrated.

For details, see Creating a Migration Task and Creating a Migration Task Group.
