when I trying to deploy it gives me this error. this userID field is something very critical

Hey @Dulara Malindu Colombage 👋 There shouldn't be any breaking changes to upgrade. What have you added to the

userID

field while upgrading?

OMG!. nopz. I didn’t add anything. but noticed prisma introspect generated new data model has changed it’s field type from ID to string automatically

I would then suggest to take a backup via

prisma export

then apply the changes and then import your data again via

prisma import

as described here.

I have a large number of data on my database. nearly 7GB. is it ok?

Yes you can change to ID (don't add the

@id

directive as that should be only on the primary key). Bug I would still suggest taking a backup first before deploying.

I will try deploying without @id directive.

Just

prisma export

for now so that restoring is possible in case of an error.
