Table 1 Checking whether the destination database has sufficient storage space

Check Item

Whether the destination database has sufficient storage space

Description

Check whether the destination database has sufficient storage space. If storage space is insufficient, the migration will fail.

Failure Cause and Handling Suggestion

Failure cause: This item cannot be checked because the source database fails to be connected.

Handling suggestion: Check whether the source database is connected.

It is recommended that the size of the destination database disk be set to the smaller value of the following two values:

  1. 2.5 times the size of the data to be migrated in the source database.
  2. The size of the data to be migrated in the source database plus 200 GB.
