Cloud Migration BC 25 Onprem - BC Online - issue with missing table extension values

Posted on by MS-03121326-0
Hi everyone,

On onprem Business Central there are few custom PTE tables and table extensions that I want to migrate. I run data migration in cloud migration management. All table data migrated succesfully, but none of the values from the table extension fields were migrated. For example for Item Ledger Entry table I can see in Migration Table Overview "PRODUCTION$Item Ledger Entry$437dbf0e-84ff-417a-965d-ed2bb9650972$ext" with status "succesful". For example some data SFI extension replicated succesfully, but custom field "Mix ID" did not. 

In SQL extension fields for Item Ledger Entry are stored in "PRODUCTION$Item Ledger Entry$437dbf0e-84ff-417a-965d-ed2bb9650972$ext". I have also created custom table mapping. Fields names and types are the sam in onprem and online. The only difference is a different extension ID. 

Looking forward to any advice!

    Hi There,
     
    If the extension app id was changed from what it was initially, the upgrade will not transfer any data for custom fields. You have the change the app id back to what it was initially for the data migration to be successful.
     
    Hope it helps.

    Hi,

    as I understand this case applies to table extensions? I am asking because for table migration I was able to migrate them between different extensions (different app id) - it was only necessary to have the same field names and keys.
