@joerodgers
Thank you for this great script. Just run and the result is outstanding.
@philippe-entringer - Sorry, not much I can do, it's very likely throttling in SPO from trying to download that many items.
Anyone getting the following errors / know how to resolve them?
I also executed a workflow 7 times on Friday, ran the latest version of the modernization tool on Saturday, then ran this supplemental script. The runs for that specific workflow did not show up (0 in ExecutionCountLastSixtyDays column).
@MAKelly2, I think the issue was due to only having 1 result found in the WFH list. I made some tweaks that I think will resolve that issue, please try again with the updated code.
No errors with the updated code! Thanks a ton! You're help and quick response are very much appreciated.
@joerodgers do you know why we would be getting a 401 unauthorized for every site?
When we hit this line...
$web = Get-PnPWeb -Connection $connection
We have the azure app admin consented for application permissions for Sites.FullControl.All so not sure why there's a 401 error?
Any ideas?
@ryanellis42, that seems very strange, since you would have connected to each site collection already to pull the primary owner login and email address. You might try setting a breakpoint on that line and validate the values of the $connection and $webUrl variables. Maybe it'll shed some light on the issue.
The data that this script generated was critical in our 2010 Workflow migration. Thanks a ton. Is there any possibility of getting 2013 Workflow usage details?

I've noticed that if you make a modification at line 813 in order to filter modernizationScannerRows by Subscription Name (instead of Id), it will successfully return workflow history list count for 2013 workflows as well, as long as they're logging info at such list.
foreach( $aggregrate in $aggregrates )
{
# $row = $modernizationScannerRows | ? 'Subscription Id' -eq $aggregrate.Name
$row = $modernizationScannerRows | ? 'Subscription Name' -eq $aggregrate.Name

@joerodgers, For large WF History list (2739098 items),
it fails on the line 185 when retreiving items Get-PnpListItem (image attached)
Any suggestion here ?
Thanks
