解像度
LPS-150879に記載されているように、DXP 7.4 Update 34+（U34+） にアップグレードする場合は、 Upgrade Process for Search Experiences を実行して、 SXPBlueprint および SXPElement エントリーに必要なデータベース変更を反映させる必要 があります。 アップグレード後、Search Adminから各エンティティのインデックスを再作成してください。
保留中のモジュールアップグレードがある場合、サーバーコンソールに以下のメッセージが表示されます。
2022-07-13 08:19:38.856 WARN [main][MainServlet:407] Required upgrades in modules are pending. Run the upgrade process or type upgrade:checkAll in the Gogo shell to get more information.
変更点の詳細およびモジュールアップグレードの実行方法については、 LPS-150879 および https://learn.liferay.com/dxp/latest/en/installation-and-upgrades/upgrading-liferay/reference/database-upgrade-options.html を参照してください。
既知の問題
(Updated, August 2, 2022) アップグレード処理が正常に実行されない、またはブループリントのデータが壊れる可能性のある問題が発見されています(LPS-158873, LPS-158782)。 これらの問題は、将来のアップデートで修正される予定ですので、アップグレードを待つことをお勧めします。
(2022年9月19日更新)。両方の問題は DXP 7.4 U37 で解決されており、 Liferay Enterprise Search Experiences v1.1.0には影響しません。
