| foreach ($collectionname in $collectionstomigrate) | |
| { | |
| Write-Host "Porcessing the collection $($collectionname)" | |
| & c:\tools\dt–1.7\dt.exe /s:DocumentDB /s.ConnectionString:"AccountEndpoint=$sourceaccountname;AccountKey=$sourceaccountkey;Database=$sourcedatabase;" /s.Collection:$collectionname /t:DocumentDBBulk /t.ConnectionString:" AccountEndpoint=$targetaccountname;AccountKey=$targetaccountkey;Database=$targetdatabase;" /t.Collection:$collectionname /t.CollectionThroughput:1000 /t.UpdateExisting:true | |
