Error migrating portal from dev to prod

Hi All


I’ve just built my first PowerApps Portal in dev and I am trying to migrate it to prod. I have followed the post below but when I try to access the migrated site I get an error. I hope someone can help


Migrate portal configuration - Power Apps | Microsoft Docs


A new portal was provisioned in our prod environment. The configuration data was exported from dev and imported into prod for the following schemas:


Site Settings

Content Snippets


Web Templates

Page Templates

Web Pages

Entity Forms

Entity Lists

Web Link Sets

Web Roles

Web Page Access Control Rules

Entity Permissions

Web Files and Notes attachments


I ran ‘Run Portal Checker’ and everything passed


I turned off custom error messages and saved error logs to Azure Blob Storage


The error I get when attempting to access the migrated portal in production is


‘Server Error in '/' Application.

The resource cannot be found.

Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.  Please review the following URL and make sure that it is spelled correctly.

Requested URL: /

And the error in Blob Storage

To display Page Not Found page localize it in English language.

The Page Not Found page is in English



Also when I attempt to edit the production portal after a few minutes of the ‘Getting things ready’ message I get ‘Something Went Wrong’



Any ideas

Hi @paulsnolan,

This error means that portal tried to access the root page of the portal, cannot do it, tried to redirect to default 404 page and cannot find it either. I would advise you open Admin Portal and check if the portal is pointing to proper D365 instance. Also, I would advise you to restart portal - sometimes some changes are not reflected especially after migration. If this doesn't help I think you need to open a support ticket with MS.

Hi OOlashyn


Apologies for the late reply, been on festive break, Happy New Year.


Tried your suggestions but neither worked. However we did manage to fix the issue, but it was a bit ‘left field’. The clue was in the error text where it refers to the Page Not Found page being localized in English language. I’d checked all the pages in the migrated portal and they were set to English. However my colleague, using Portal Management’, removed the English language from the Page Not Found Web Page and re-added it (with no save in between) and then Save & Close and the page appeared. We tried this with the Home page and voila the migrated site came up. We then went to the Website in Portal Management and did the same for the Default Language. I can now also edit the migrated portal. Have you ever come across this with page languages? Thought I would share to save anyone else my pain.


Hi @paulsnolan ,

Interesting finding. I didn't experience this issue in particular, despite using portal with couple of languages. I had similar issue but in that case missing page just didn't have a version with proper language. Good to know and thanks for sharing!

Hi @OOlashyn 

Further info re this issue. Doing a dummy update of the Default Language for the Website, as mentioned above, doesn't update the language for all the pages in the portal. We still had to do a dummy update for an individual page to make the page available.
