I upgraded from version Cumulus MX 3.28.6 b3283 to version Cumulus MX 4.0.1 b4023
The upgrade went well with no issues running the MigrateData3to4.dll or any other issues during upgrade.
I used the MigrateData3to4.dll from the Cumulus MX v4.1.0 build 4024 per this Forum Post I posted earlier viewtopic.php?t=22292
However, I noticed in the Dashboard under Utils > Latest Errors I have the following errors:

Any ideas what I need to do to fix the errors?

Re: Upgraded to V4.0.1 Build 4023 Numerous Errors with Dayfile
There definitely is an error in MigrateData that goes with version 4.1
@freddie: I would suggest to withdraw CMX4.1 and issue a warning against its use of the corresponding MigrateData.
@Igeitner: I would revert to 4.0.1 and the corresponding MigrateData or wait until things get solved on return of Mark.

@HansR: I used the MigrateData3to4.dll that is included in CumulusMX v4.0.1 b4023. There are no longer any errors in the Dashboard > Utils > Latest Errors!
Thank You,

Could someone please post a v3 day file that does not convert? I cannot reproduce the problem on my laptop.

There might be one here, or was that a converted one…

I’m quite sure I have seen some other thread also but cannot find it.
