Hello. I'm struggling with a manual migration of my K2 items and categories going from J1.5 to J2.5. I followed the steps outlined in getk2.org/documentation/tips-a-tricks/item/311-manually-migrating-k2-content-from-joomla-15-to-17 and everything is actually moved over great EXCEPT for one portion...

The "params" field in the k2_items and k2_categories tables do not convert to the new Joomla 2.5 style. What I mean by that is...

In J1.5 the params field looked like:
inheritFrom=2
theme=
num_leading_items=2
num_leading_columns=1

In J2.5 the params field needs to be:
{"inheritFrom":"0","theme":"","num_leading_items":"0","num_leading_columns":"0", and so on.

This is the case for both the categories and items params fields.

Question is, how do I migrate my J1.5 categories and items to be compliant with the new way to store params values in J2.5?

Thanks in advance!
