Bulk "Undelcare" and "Send To" in SharePoint

Recently i have a small issue with Information management policies in one of the sharepoint environments.
So as a result i have nearly 10,000 records which need to be moved across to another Site collection.

In order to undeclare a record, i need to go to complaince details of each document and click that "Undeclare record" button.

Now coming to "Send To" functionality, i need to open context menu of each item and select the specific "Send to" connection.

Now i cannot do this for 10,000 documents. So this is why i love Powershell.
