Can I migrate K2 after I am already on Joomla 5?

Not with K2 running. K2 has no Joomla 5 release. Restore or clone a Joomla 3.10 copy that still has K2, migrate there, then bring native articles forward. If you only have a Joomla 5 database with leftover #__k2_* tables, you need a specialist extract, not the administrator component.

Does Migrate K2 Pro delete my K2 data?

No. It only reads K2 tables. Reset removes the Joomla articles, categories, tags, fields, and redirects it created. K2 stays until you uninstall it yourself.

Will my old K2 URLs keep ranking?

They can, if 301s exist and System Redirect is on. The component writes /component/k2/item/{id} and /component/k2/item/{alias} . Custom SEF layouts need extra rows. Rebuild equivalent article and category menu items so canonical URLs are clean going forward.

Are extra fields included?

Yes, for published K2 extra fields and their values. They become Joomla custom fields on com_content . Unpublished extra fields are skipped. Media paths inside values are rewritten to the new image folder. For groups, category assignment, Automatic Display, and overrides, use the custom fields replacement guide .

Do comments and attachments become Joomla comments and article files?

No. Export them. Joomla 3 has no core article comments. Attachments are files plus metadata. Import into a comment extension or a file field after you know the new article IDs.

How long does a migration take?

Small sites (hundreds of items) often finish in under a minute. Tens of thousands of items take minutes in the component, or hours in CLI on a large news archive. Batch size and server PHP limits dominate, not the mapping itself.

Should I go to Joomla 5.4 or Joomla 6 after K2 is gone?

Go to 4.4 first, always. Then 5.4. Choose 6 only when the Pre-Update Check and every remaining extension are ready. 5.4 is the safer landing if a cart or CCK is lagging.

Migrate K2 to Joomla Articles Before You Upgrade

Stay on Joomla 3.10, copy K2 into native articles with 301s, then uninstall K2 and climb 4.4 to 5.4 to 6. Upgrading first leaves items trapped.
