We recently completed migrating one of our site to Online, which consist of several form library with over 10k records utilizing Infopath forms. After completion, i tried to open those documents, found out that it's still pointing to old site URL, and only opens with desktop infopath tool.
Troubleshooting that i have done so far:
1)Updated Data connection to a new Site URL.
2) Made sure that open with browser feature is enabled at library setting .
3) Tired adding new record, edit it and didn't have any issues with a new record.
4) Tried running Repair.ASPX ( RELINK feature) within Form library and were able to relink 3k out of 7 k records. and have doing it for over 10 times now.
5) and now i am trying to relink every single records. And dont think its worth investing that time for relinking 7 k records individually.
