"ZODB Mount Points" are implemented at a very low level (much below Plone)
and (if set up correctly) are (almost) transparent to higher levels
(such as Plone). Thus, all Plone versions should be able use them
in the same way.

The normal instance recipe does not support this setup
directly (in the same way as the single mount point setup).
But it supports a general purpose configuration option
for adding arbitrary definitions to the generated "zope.conf".
Use this to define the storages and the associated mount points
(likely, your old installation has done this as well).

>(The configuration in Plone 3.3.5 fails in 4.3.3). The last release of collective.recipe.filestorage was in 2010.

I do not know "collective.recipe.filestorage". Should its sole
purpose be to help with the configuration of the storages and the
corresponding mount points, you could do without it.


> (2) Or should I put 10 sites onto 1 Data.fs? We bought 2 server machines, planning to divide up the 19 sites, 10 on one server and 9 on the other server, to increase web server performance.

Likely, there was a reason for the original separation (one might
be easier restoration in case of some catastrophical destruction in one site).
