Version upgrades sometimes require changes to how features store configuration
|
|
information and data in system indices. The feature migration APIs enable you to
|
|
see what features require changes, initiate the automatic migration process, and
|
|
check migration status.
|
|
|
|
Some functionality might be temporarily unavailable during the migration
|
|
process.
