Business Central 2019 Wave 2 (15.2) upgrade to 2020 Wave 1 failed - Page 1752 was not found

[Wiechardt]

Hi there,

I ran into a problem upgrading a Business Central 2019 Wave 2 database (15.1.37881.38071) to Business Central 2020 Wave 1 database (16.0.11240.12076) - the old and new databases are both the GB version of the application/database.

I would really appreciate assistance with this issue.

Describe the bug I am following the steps in "https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/upgrade/upgrade-unmodified-application" and when I run this command below:

Sync-NAVApp -ServerInstance BC160 -Name "Base Application" -Version '16.0.11240.12076' -Mode ForceSync

I get this error:

_Sync-NAVApp : The metadata object Page 1752 was not found. At line:1 char:1

• Sync-NAVApp -ServerInstance BC160 -Name "Base Application" -Version ' ...

• 
  + CategoryInfo          : InvalidOperation: (:) [Sync-NAVApp], InvalidOperationException
  + FullyQualifiedErrorId : MicrosoftDynamicsNavServer$BC160/nav-systemapplication,Microsoft.Dynamics.Nav.Apps.Management.Cmdlets.SyncNavApp_

This page is the DataClassificationWizard.Page.al page.

To Reproduce As explained above.

This is my Get-NAVAppInfo:

• AL Language: 5.0.254558
• Business Central: 16.0.11240.12076

Hi, I wander why do you have the 15.X versions of System App and Base App still installed? Here it says that all apps should be uninstalled/unpublished first https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/upgrade/upgrade-unmodified-application-v15-to-v16

Hi there,

You are 100% correct, I saw that too and thought it was meant to still be there at that stage.

I followed the steps in the help topic you posted and I managed to upgrade the database without a problem.

Thanks so much, you can close this issue as resolved.
