Changing Thing template of a thing in dev then trying to change the one in prod

[JK_10744682]

Hi all,

We have a thing in prod that was pushed from our dev environment. That thing uses a template that is outdated. We want to change the template to a new one that we are now using in dev, but pushing gives this error:

How can we go about changing the template in prod? We are unable to manually delete it directly from prod since the entity was pushed there.

To clarify: You cannot delete the KT.PostgresSQLDatabaseConfig thing in Prod? With what error?

I'm not familiar with this "Deploy" dialog you show.

If this deploys this thing as part of an extension you can only deploy a new extension which does not contain this thing. And then a new extension which includes it with the correct thingTemplate.

You cannot change a ThingTemplate of a thing. You need to remove the thing and recreate it with wanted Template (unfortunately).

Hi @JK_10744682

A thing template basically defines what a Thing is. If you created a Thing from composer by giving its name and Thing Template, both name and Template are not modifiable after saving.

My guess is Solution Central works in similar way hence giving this error message.

Can you please try removing the affected entity KT.PostgresSQLDatabaseConfig thing manually in Prod and then deploy the solution from dev again?
