Hi
First of all, thank you for the update!
I have a question, what does it look like when we have JL version 3 and what does the transition to JL6 look like?
Is this possible or is the database different?
Regards.
Hi,
Thanks for the message.
Migration from JL3 to JL6 will be possible.
JL6 is built on the original database tables, but some changes are required.
For example, the default datetime value in JL3 was 0000-00-00 00:00:00, whereas in Joomla 6, it is NULL.
Therefore, a helper script will be created for this purpose and provided free of charge, just like the new JoomLeague 6.X itself.

Thank you for answer.
Migration from JL3 to JL6 will be possible.
Please clarify
Will be in feature or is possible now for testing 
Hi Marcin,
Currently, I am testing the migration process on my local environment. I plan to release a new pre-alpha version very soon, which will include this import functionality.
However, please note that the data migration itself will only be possible via an external web service at https://migrate.klucon.cz. During development, I ran into various PHP execution limits and timeouts with large datasets. To solve this, the migration tool was rewritten in Python, making the entire process extremely fast and reliable. I most likely won’t be pursuing a standalone PHP migration script anymore.
You can read more about data privacy, security, and the technical documentation here:
https://docs.klucon.cz/import/joomleague3
Additionally, the upcoming version will introduce support for new sports, specifically focusing on running disciplines, joggings, and marathons, as discussed here: https://github.com/klucon/com_joomleague/issues/16
Best regards,
klucon
