Background information

After you create a migration project, Advanced Database & Application Migration (ADAM) automatically runs a precheck.
Note This operation is supported only when you migrate data to PolarDB-O databases or ApsaraDB RDS for PPAS. If you migrate data to other databases, ADAM automatically skips the precheck.
  • Check the permissions of the account of the destination database. If your account does not have the required permissions, recreate a migration project. For more information, see Why does the account of my destination database not have sufficient permissions to migrate data?
    • Check whether the account of the destination database has the permissions to create users.
    • Check whether the account of the destination database has the permissions to authorize users.
    • Check whether the account of the destination database has the permissions to create and delete schemas.
    • Check whether the account of the destination database has the permissions to create and delete data definition language (DDL) statements.
  • Check the destination database plug-ins

    Check whether the required plug-ins are installed on the destination database. If a plug-in is not installed, execute the corresponding SQL statement to install the plug-in. For more information, see Why is the plug-in of a destination database missing?

  • Check the version of the destination database

    Check whether the version of the evaluated destination database is the same as the version of the destination database that is used to migrate schemas. If the two versions are inconsistent, recreate a project to evaluate the destination database. For more information, see Why is the specified database version in a database evaluation project inconsistent with the actual database version?
