If I want to move a core from one physical machine to another....
If I want to move a core from one physical machine to another,
is it as simple as just
scp -r core5 otherserver:/path/on/other/server/
and then adding
<core name="core5name" instanceDir="core5" />
on that other server's solr.xml file and restarting the server there?
PS: Should have I been able to figure the answer to that
out by RTFM somewhere?

If "core5" is the local Solr data directory for that core,
yes that should work. Of course, you will also have to ensure
that the schema, and other configuration details, e.g., in
solrconfig.xml, match.

Maybe not specifically noted, but copying Solr's index by
copying the data directory to a new machine was always
possible, as far as I know.

It's not; for our needs here, we have not set up replication through SOLR.
We are working through OOM problems/performance tuning first, then "best
practices" second. I just wanted the OP to know that it can be done, and how
we do it. :)

How is this better than replication?

Ron,
In our current environment I index all of our data on one machine, and to
save time with "replication", I use scp to copy the data directory over to
our other servers. On the server that I copy from, I don't turn SOLR off,
but on the servers that I copy to, I shutdown tomcat; remove the data
directory; mv the data directory I scp'd from the source; turn tomcat back
on. I do it this way (especially with mv, versus cp) because it is the
fastest way to get the data on the other servers. And, as Gora pointed out,
you need to make sure that your configuration files match (specifically the
schema.xml) the source.
