moving existing terms to a different taxonomy while keeping existing usage

You can freely change the parent of any term with the existing interface.

This feature is needed

Absolutely. Even two versions of drupal after this issue was introduced, the taxonomy module remains pretty static. I can't imagine the number of times I have moved terms around within a vocab and across vocabs and it is a nightmare, especially when you have lots of terms.

Taxonomy is a difficult concept to grasp, so having the ability to move terms around dynamically would be a great usability feature.

+1 for this feature

I manage a ever growing website and I regularly find the need to reorganize, combine, split, etc. taxonomies and terms - to accomodate a new module, for example. I don't think this feature needs an interface. There is already a selection for parent in the edit term form. This selection could be made to include other taxonomies in the same way that the book module's parent selection includes other books or motf's selection includes all menus (excepting the one's you exclude, of course).

On the other hand, such a comprehensive selection tool would likely become unwieldy with large vocabularies. But it would be worth it to me. Could this be accomplished at the module level - allowing those that have a pressing need to have it available, while not cluttering the parent selection for other folks?

if the taxonomy forms have been properly apified (this needs checking) then it might be possible to move a term elsewwhere by adding an form to the "edit" field. this coul dbe done in a contrib module.

vocabularies grow over time, so splitting would come in handy ...

first thought one only needs to change the parent of the root of the sub-tree to move (in term_hierarchy), but all terms in the sub-tree have vids specified in term_data that need to be changed, too.

new features go into devel version.

(Moving x.y.z version to a real version number) Feature Request => 6.x-dev

Pl. ignore if I have misunderstood this issue
----
In case this helps anyone, there is/used-to-be a contrib module called taxonomy_switch that let you move terms from one vocab to another. It worked pretty smoothly when one term was moved to another vocab but when I tried moving a number of terms, they disappeared from the vocab and I couldn't find them on the admin page (although I suspect they were still in the taxonomy table) to move them back.

The category module has a bulk_edit contrib module that does this. It is occasionally buggy but works and might be a useful place to look for ideas if anyone is interested.

Thanks, bert.

There is any solution for Drupal 6? Taxonomy switch module works only for Drupal 4.7 and is only a dev release for 5.x.

Any movement on this one? As ionuts points out, the workaround module hasn't had any updates since Nov 2007. Seem to me this should be part of the core Taxonomy module...

Thanks.

module taxonomy manager can do something similar, but not this.

This feature would save me time.

This feature is really needed.

Subscribing. To a 6 year old thread... wow.

Subscribing

Does anyone know how one would use the Drupal core APIs to perform the desired operations (in 5.x, 6.x, and 7.x), or would this need to be done using raw SQL queries (I'd like to avoid performing raw SQL queries if possible.)

I'm asking this question because I'm hoping the core API has the functionality we need; this kind of plumbing should not be left to module developers.

Ideally, there'd be a core API taxonomy_move_term(...) that would manage the low-level details and shield module developers from the complexity of the database structures, and help prevent damage to the database by contributed module bugs.

@grateful_drupal_user - i recommend you join the #drupal channel on IRC and ask this question. good luck in your quest!

It`s still needed...

You'll find useful info here: http://drupal.org/node/382944 and here http://drupal.org/project/taxonomy_manager

This is won't fix for D6 or D7, if you'd like to see taxonomy_manager added to core, open a feature request against D8.

Just experience this issue, first I move it by SQL manually but since my client need to move very much terms so I create this module:
- https://www.drupal.org/project/term_manager

Current features:

1. Move term to another Vocab
2. Merge term

I see another module support Merge Term, but its create new Term even the Target Term same as one of Source Term. This module try to use existing term, not create new term.

Updating title, tags and version number based on recent announcement at https://www.drupal.org/about/core/blog/new-drupal-core-branching-scheme-...

Would like to ask around if there is still enough interest to keep this open as future FR for core. So I opened it temporary just in case. If not feel free to close it again.

Fixed title regarding the comments and the actually wish behind this and to make the intention clear regarding "moving vs replacing".

This is still a problem in Drupal 10. There was this module "Taxonomy manager", that was solving this problem in Drupal 7, but the version for Drupal 8 and ahead don't have this feature anymore.

...but the version for Drupal 8 and ahead don't have this feature anymore.

from #32, what makes

if you'd like to see taxonomy_manager added to core, open a feature request against D8.

from #28 obsolete as solution.

So we need to find a new approach. I think moving terms is an interesting feature for bigger existing projects and there seem to be no way ou tyet for this.

Vocabularies are bundles now, which makes this even more complicated than it used to be because there are also fields to worry about.

https://www.drupal.org/project/convert_bundles in contrib might be an option.

Because of the bundles/fields issue, I can't see us ever doing this in core, moving to 'needs more info' but I think it should probably be closed as 'by design'.
