Move emails in bulk

[sprasad]

At the moment we created an 'inbox archive <month>_<year>' each month in each of our 4 mailboxes.
We then create a 6 month Archived Folder and move these from the monthly folder to the 6 month folder.

We now need to move the 6 monthly emails into a central folder for each year e.g. 2019/2020, etc
However, the 2 folders we have for the year 2019 has >50k emails and currently, you can only move 500 emails at a time.

Is there any way to Bulk Move the whole Archive Folder to a new folder (similar to the options you have for "Empty Folder" & "Delete Folder"?)
