Archive SharePoint List that contains 50K+ Items with attachment

[VeGETzX]

Hello,

I now finding a way to archive items that older than 2 years in a SharePoint Online List that contains about 50,000 Items.

After some digging the data, The number of items need to be archived should be around ~30000 items.

I try using the flow and use SharePoint batch API to create a copy of the item that need to be archived in the new list then remove the original item from old list.

The batch API is fast enough but there are one problem, My list have attachments and it's look like the batch method can't deal with attachments.

Any suggestions would be greatly appreciated and thank you in advance.
