What Should I Do If the Migration Source Is Oracle and Error Message "snapshot too old" Is Displayed?
This error is caused by Oracle constraints. During the migration, no data can be updated, deleted, or added in the source table. You can increase the value of UNDO_RETETION and adjust the size of the UNDO tablespace.
