• Labels:
  • 7.2-should
  • QA-AUTOMATION
• Fix Priority: 3
• Git Pull Request: https://github.com/brianchandotcom/liferay-portal/pull/73091

Steps to reproduce:

1. Start up a new Liferay.
2. Go to the Global site > Publishing > Export and create a new export process.
3. Select only "Pages" to export.
4. Download the lar file
5. Create a new instance and sign into it.
6. Go to the Global site > Publishing > Import and create a new import process.
7. Import with mirror strategy.

Expected: The import process finishes correctly.

Observed: The import process fails due to duplicate entry '37101-Blog' for key 'IX_A075DAA4'. Clicking on "Show More Details" shows the message:

An unexpected error occurred with the publication process. Please check your portal and publishing configuration.
The Layout Page Template Entry Blog could not be imported because of the following error: Could not execute JDBC batch update.
