BC17 Upgrade fails on Database Conversion

Doing an upgrade from V15.5 to V17.0 and it fails doing the database conversion with an SQL timeout after 1 minute.

This is on an Azure VM ( Standard E4s v3 (4 vcpus, 32 GiB memory) ) connected to an Azure SQL db (31GB).

Steps followed from here:

https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/upgrade/upgrade-unmodified-application-v15-to-v17

I have increased the DTUs to 200 and run exec sp_updatestats on the database. Still fails:



PS C:\windows\system32> Invoke-NAVApplicationDatabaseConversion -DatabaseServer "sql04.database.windows.net" -DatabaseName "BCTest" -ApplicationDatabaseCredentials (Get-Credential)



cmdlet Get-Credential at command pipeline position 1

Supply values for the following parameters:

Credential



sql04.database.windows.net

If you convert the database 'BCTest' on the 'sql04.database.windows.net' server, you will no longer be able

to open it with older versions of Dynamics 365 Business Central.



We strongly recommended that you make a database or transaction log backup in SQL Server before the conversion.



Note that the conversion removes any modifications that you have made to system tables.



Do you want to continue?

[Y] Yes [N] No Suspend [?] Help (default is "Y"):

Does anyone have an idea, how to make this work?
