Sharepoint List

I know this already has best answer but the initial question was to use powershell and, at least I think so, to move List with data from Tenant A to Tenant B. If this is something that simple we could do it using following commands in PnP Powershell:

 # step 1. connect to some site where is the list on tenant A
 Connect-PnPOnline -Url "https://SiteUrlFromTenantA"
 # step 2. get list template
 Get-PnPSiteTemplate -Out "C:\TempDemo.xml" -ListsToExtract "testList" -Handlers Lists -Force
 # step 3. populate list template with data
 Add-PnPDataRowsToSiteTemplate -Path "C:\TempDemo.xml" -List "testList"
 # step 4. disconnect from tenant A
 Disconnect-PnPOnline
 # step 5. connect to some site where is the list on tenant B
 Connect-PnPOnline -Url "https://SiteUrlFromTenantB"
 # step 6. apply the list template with data
 Invoke-PnPSiteTemplate -Path "C:\TempDemo.xml"

I hope this will be of any help 🙂 

Numberone1 Can you please explain more about your requirements? what is "arrival tenant" & what exactly you mean by "integrate"?

If you want to copy list/site/tenant structure, check this documentation of PnP provisioning engine: Introducing the PnP provisioning engine
