[Question] Can I change Fied type from string (UiType: 1) to recordNumber (UiType: 4)?

[blu-IT]

Description

Hello,

I want to change a field type for my customer accounts/numbers. I created some time ago an own field

System Name: account_no2
Field type: string (UiType: 1)

because I wasn't satisfied with already implemented "Account number" of YF

System Name: account_no
Field type: recordNumber (UiType: 4)

Now, when trying to implement filters and search masks, I saw that I had implemented my own field as "string (UiType: 1)" what makes creating filters for me more complex. I think "recordNumber (UiType: 4)" would fit better.

But can I change that field directly in the database without loosing/damaging existing data in that field?

Thanks!

Regards,
