Hi Russell,

You would be best off going for 1.4.1 as this contains a lot of bug fixes to
1.4
You do not need to go 1.3.2 -> 1.4 -> 1.4.1, you can go straight to 1.4.1

It depends on the size of your database, and the availability of a test
machine.
In theory, on a medium-sized database such as yours (only a few thousand
items), it should take less than an hour. If you have a test machine, you
can test it all first, and then do it on your production machine.
You can get the code on the machine and compiled in advance. All you then
have to do is to stop tomcat, backup your database, run the database upgrade
scripts, update your dspace.cfg file, and deploy the new DSpace code to
tomcat. If things mess up (which they shouldn't!) then you have a backup of
your database which you can restore, and roll back to 1.3.2
The tricky part will be if you have any customisations to the code or to the
pages. If you have a test machine, you can test these in 1.4.1, but if you
don't you'll have to give yourself more time to test them once you upgrade.
If you don't have a test machine, another option you have is to run the two
versions simultaneously by changing the names of the war files (e.g.
dspace141 and dspace-oai141 and pointing them at a second copy of your
database. You can then make sure you are happy with 1.4.1 whilst still
running 1.3.2, and then change over one day by upgrading the 1.3.2 live
database and changing the war file names back.
I hope this helps,
Stuart
