Hi
I’m trying to upgrade Umbraco and forms from Umbraco 14 to Umbraco 17. I don’t know how the previous upgrades may have been done in case that is important to know.
I’ve done the migrations and then went from Umbraco 14 to 17 and when run the site I get an error about forms
The migration plan “UmbracoForms” does not support migrating from state “12345-678-------”
I checked Migration IDs | Forms | Umbraco Documentation and the guid is not listed. To overcome the problem can I clear the database value where the guid is listed and try again with 17? Or what is the solution to resolving this problem?

What is the Migration ID? I’ll see if I can find it.
Hi @KeithViking
Can you try Umbraco Forms 17.5.0 (released today), as that contains a fix for this exact issue (assuming you are seeing the same GUID?).
This is the issue raised yesterday:
opened 11:26AM - 19 Aug 26 UTC
closed 07:28AM - 20 Aug 26 UTC
state/sprint-candidate
status/needs-docs
state/reproduced
affected/v17
affected/v18
release/17.5.0
release/18.1.0
### Which Umbraco Forms version are you using? (Please write the *exact* version… , example: 13.4.0)
13.9.9 to 17.4.8
### Which Umbraco version are you using? (Please write the *exact* version, example: 13.5.2)
Latest of 13 and 17
### Issue summary
After applying the patches yesterday, I am now running into an upgrade error I didnt have before:
``` Umbraco.Cms.Core.Exceptions.BootFailedException: The migration plan "UmbracoForms" does not support migrating from state "6149738f-25bd-44ac-9c1d-d66bbe9d4e2b".
-> System.InvalidOperationException: The migration plan "UmbracoForms" does not support migrating from state "6149738f-25bd-44ac-9c1d-d66bbe9d4e2b".

```
I had Claude look at the two releases:
It appears 17 doesnt have a migration path that includes `6149738f-25bd-44ac-9c1d-d66bbe9d4e2b` the last comment state is `7e170195-cab7-48ca-98c7-bbcbd5cfda95`
thanks
