@parmen ,
Just seen your question.
I could give you a definitive answer if going from my plug-in to another, but I’m afraid that you are going to have to do a small experiment to find out whether easy or more complex.
Key is to know that the terms and links to objects use only the taxonomy slug. That is, there is no DB element to hold details of the taxonomy itself.
So if you look at a taxonomy created by Simple Taxonomy Refreshed, you will see admin options to Modify, Export PDP, Delete and Flush & Delete.
The difference between these deletion options is that Delete removes the options that you have set up, but Flush & Delete also deletes all the taxonomy terms and links.
You need to know what does your existing plug-in does about taxonomy term deletion. I cannot tell you that, but you can do a little experiment.
1. Create a new taxonomy using your existing plug-in.
2. Add a term or two and add it to a post or two.
3. Delete the taxonomy using your existing plug-in.
You will either have the terms still in your DB, or not.
4. Create the taxonomy using Simple Taxonomy Refreshed. It is critical that you use the same slug as in step 1.
You should see if the terms and links have carried over.
If they have, then you’re in luck, and you can do the same process of steps 3 and 4 with your existing taxonomy (though, as always, make sure that you have a backup).
If not, then you made need to move them with SQL so that the deletion process finds nothing to delete. You then move them back. This is not difficult, but may be outside your comfort zone.
[There will be 2 SQL statements to move them out, and 2 to move them back.]
Hope this is of use,
Neil James
