Error: Manifest data not found in archive (Snapshot Migration)

Hi. I read and checked offered suggestions in the following posts already:

I have made a snapshot backup from my site - I am trying to restore this backup to my new site where I get the error, "Error: Manifest data not found in archive".

I tried saving to and restoring from both localhost AND dropbox. I get same result either way.

I checked all zip files and the manifest.txt file referenced, DOES exist in all zip archives.

I checked version #'s of snapshot and wordpress and everything else, between both sites ... same.

NOTE: each site is with a different host. I am thinking that the php version difference could be the issue. The source site is using PHP 5.2.17 and the destination is using PHP 5.6.17-pl0-gentoo. If this is the issue, how do I make such a change manually?
