Plan change to country and region in M-files

Hi,

We plan to update the region and country in M-files.

Example

Region

The words "Middle East South Asia (MESA)*Existing* is to be replaced with "Middle East South Asia, Africa, Türkiye (MESAAT)*Africa & Turkiye will be added*.

Country

Aside to India, Saudi-Arabia, Turkiye and Africa will be added

Aside to Belgium, Italy, Poland, Portugal, Turkey will be removed

Execution

I believe this can be also done in M-files admin > Vault > Metadata Structure Flat View > Value List > Countries > contents > add/delete (edit)

same goes to Regions

Question

1. what will happen to these existing documents if they tweak the M-Files Admin app to reflect the above changes? 

2. Do they need to re-upload these existing affected documents on M-Files app? 

3. Do they need to manually update the metadata of ALL these existing affected documents on M-Files app? 

4. Will there be other issues or next steps that I need to be aware of

Note

I already open a ticket to M-files support but no response since May 19

Regards,

Tash
