After migration of Powerapp: Unable to find the default new form for list

[sjorz70]

I duplicated my Sharepoint within the same tenant with ShareGate to have the copy identical. I downloaded the exported PowerApps and forms and use dthe FlowPowerAppsMigrator tool to update the Source site to the Target without moving lists/libraries. After the migration that showed no errors I imported the PowerApp via make.powerapps.com with Import as New and update the name of the powerapp.

After the import I could see the the app and also from the List Settings I could update the imported PowerApp.

However, if I click New or Edit a list item, it gives the message "Unable to find the default new form for list for ..."

Anyone who can help me out? it looks like new.aspx and edit.aspx is messed up. We do not have MS SharePoint Designer anymore to update this.

Hi @sjorz70, can you delete the problematic list(s) and use ShareGate again. But this time, unselect the "Customized list forms" in your configurations section of the copy options screen

Hello Zerg00,

After that, I can re-import the converted list right?

[Zerg00s]

Yes, you need to re-run the migrator to convert the Power App(s) to be compatible with the new destination list.

Hi Denis, We deleted the imported lists and copied them with ShareGate as new lists with the default SharePoint form. Then I converted the flows and apps again and reimported these. That works. It was a bit trial and error, but the migration tool did some good work replacing the correct URL’s and Form ID’s Verzonden vanuit Outlook voor iOS<https://aka.ms/o0ukef>
