How can I change custom field type from single user selection to multiple user selection?

[Esther Amunga]

I want to change from a single user picker to multi user picker

You don't.  There's no way to change the type of a field.

You will need to add a new field of the right type, copy over any data you want to keep, and then delete the old field.

@Nic Brough _Adaptavist_ If you delete the old field, I'm guessing that will delete the info from all the issues that had the field right? 

[Nic Brough _Adaptavist_]

Correct,

if you delete the field (the header information saying "this field is here"), then the issue data has nowhere to exist, and hence simply gets deleted.

@Nic Brough _Adaptavist_ Ah, that's what I suspected. Do you know by chance if there's a feature request open to add the ability to change the field type? Thank you!

[Nic Brough _Adaptavist_]

There was, but the ones I've seen are all closed with "won't fix" type resolutions

Ah ok, hopefully we'll be able to change the field type in the future. Thank you for your help!
