Generally you cannot change the property type once you created and saved a property.

Delete the property and create a new with the correct type.

We have a property with date type in PROD. Due to BIX extraction issue, we are planning to chaneg the property type from "Date" to "DateTime".

As you mentioned above, do we need to create new property with "DateTime" instead of updating existing property. if yes, do we need to delete the existing proeprty in PROD and deploy the RAP file? Please let us know. We are using Pega 7.1.8 version.

Thank you for your support.

Pega 7 does not allow change of the property types . While it does support a few property type changes(check out article around this) - the above thing can be solved by making changes to availability.

Assume you are trying to save the same property to higher version with change in property type. Follow below steps

1) Save to higher version.

2) Make availability withdrawn & click on save.

3) Change the property to datetime & click on save.(will throw no error)

4) Check-in

5) Checkout & change the availability to yes.

6) Checkin the rule & you are good to go.

Please note that it is not a best practice to change property types. It might severely impact your application if done without due caution.

I'm facing a similar issue related to a data table property while changing the property type from Integer to Text for some business requirement.

The above approach is not working in Pega 6. Do we have any other approach in Pega 6 ?

Do a save as of property in one version and mark it withdrawn

Create the same property with same name in +1 version and make it available

Make sure you are deploying both versions in one go.
