Duplicate Tag Exception while using Publications for content updateDuplicate Tag Exception while using Publications for content updatehttps://liferay.dev/c/message_boards/find_thread?p_l_id=119785294&threadId=1234104542026-04-07T18:51:28Z2026-04-07T18:51:28ZDuplicate Tag Exception while using Publications for content updateRAJESH KUMARhttps://liferay.dev/c/message_boards/find_message?p_l_id=119785294&messageId=1234104532025-05-22T16:09:05Z2025-05-21T05:31:52Z<p>Our Liferay DXP environment, originally migrated from version 6.2 to
DXP 7.1 five years ago and then to DXP 7.3, is experiencing
publication failures. We're transitioning from a Staging-Live setup to
Publications to mitigate issues with the staging infrastructure and
network during remote publishing.</p>
<p>However, when publishing web content with assigned
<strong>tags</strong>, the process fails, returning the error:
"An unexpected error occurred with the publication process.
Please check your portal and publishing configuration. The Tag tagname
could not be imported because of the following error: A tag with the
name <<tagname>> (duplicate) already exists."</p>
<p>Liferay support suggested adding
<code>staging.merge.tags.by.name=true</code> to
<code>portal-ext.properties</code>. While this resolves the issue for
new content and updates to existing content, it doesn't work for older
content that already has tags assigned.</p>
<p>Has anyone encountered a similar problem or have any suggestions?</p>
