You'd normally use either Document Queue processing or TRIMPort. Both have comprehensive help files included. For queue processing refer to the TRIM online help - Chapter 11 - Document Queues. For TRIMPort refer to the TRIMPort online help.

Yes, Mate, ( ) I will be running TRIMport tool from Server, bringing across the electronic documents with the metadata, for 300+ staff and doing all of this 'out of business hours'... will be doing the import/migration in batches (by team/group)... and I will take your advice and test it two or three times!
When migrating 3+ million files, it took us a period of multiple weeks, over weeknights and weekends in batches. Yes, we could have done all this through the backend and not use TRIMport.... but, TRIMport took care of all the dependencies etc for us... as long as we fed it correct and bite sized import files.
One other thing you might need to look into is ensuring that your import batches do not impact on the nightly (and others) backup / maintenance regimes for your TRIM environment. We ran our batches in the early evening, ensuring that the batches were completed around 2am'ish before the backups etc kicked in at around 3am.
Another thing to consider is event, word and content indexing.... if you are importing large volumes, the indexing will still be chugging through when staff start logging in the morning etc. Again, depending on your environment, you might want to ensure that your event server/s has chugged through all (or at the very least 90%) of the events/indexing before staff log in in the morning. This will alleviate performance hits and staff not being able to search for a record they just put in because the indexing is so far behind.
All this is just based on my own experiences and my own TRIM environment, of course. Others might have different (but equally valid) guidance for you as well...
I am trying to locate information on how to use TRIMport and when searching HP Online Help I either get a message saying 'Service Unavailable' or 'Page requested unavailable'... that is why my original request was for a .pdf document from anyone.
All I can seem to find is a single paragraph describing what TRIMport is.
So, maybe in a Technical manual someone has access to there is more information on the 'how to' and 'what to look out for' when using TRIMport to Import files from a network drive into TRIM.
I think what you will find, TOT is that there is not really a wealth of information out there regarding how to tackle the intricacies of using TRIMport other then the bare essentials found in the help guides bundled with the product. That said, if you can't even find the bare bones help guides for whatever reason, let me know and I might be able to dig around for stuff to send to you.
We essentially had to learn from scratch on how best to utilise TRIMport within our own environment - and I think that is the key... you will still need to experiment and test intensely how this product will behave in your ICT environment - no matter how detailed the help guides you get. But, I'm guessing you already know that and are prepared for it.
Another thing you might like to consider if you have not already is 'parallel importing'. One of the good things about TRIMport (and TRIM) is that it allows you to import data simultaneously through multiple TRIMport clients. This can really speed up the import process (all other factors being equal).
