Want to move all photos with no exif timestamp to a new directory

[gameguy56]

I need to do a recursive search down through all folders in a directory and move the photos without an exif timestamp to a different folder so I can go through and evaluate them. Seems like this should be fairly straightforward but I actually am having a hard time getting to understand how to do something to images without tags in ExifTool as opposed modifying images based on data they have.

Thank you for your help, anyone reading this.

Try
exiftool -if "not $DateTimeOriginal and not $CreateDate" -Directory=/path/to/nodates/ /path/to/source/

This assumes there won't be any files with the same name.  If that were the case, instead of Directory, you would have to use this to add a copy number
-Filename=/path/to/nodates/%f%-c.%e

This command would be for Windows CMD.  If some other shell, change the double quotes into single quotes.
