I was using a NAS for data storage. My VAR was saying that I needed a vault to reduce crashes - they say that NAS have known issues. I set up a vault and have been experimenting, doesn't seem to help much with crashes but does have some other nice things. I am migrating.

I have ten's of thousands of files to migrate to the vault. Some are assemblies that contain parts in other folders. I can see doing this a few different ways:

1) Copy all the files/folders to the vault in one large operation over the weekend.

2) Move a small chunk of files/folders every day.

What's best practice for migrating a bunch of files/folders to the vault?
