I have been tasked with migrating a Laserfiche repository to Alfresco (Records Management module).
The Laserfiche implementation is hugely underutilized - They've scanned in about 60Gb in the last 9 years, and simply do infrequent lookups based on the full-text OCR. Only two meta-data fields are tracked: Account Type, and Client Name. That's it - no other features are utilized.
I have Googled the heck out of "migration tools", and found nothing that reads from Laserfiche. I find that Laserfiche does not support any standard export format or APIs such as CMIS or JCR.
Certainly, there are firms that do nothing more than migrate documents, but for enterprise / fortune-1000 clients; this is a small workgroup. I'm hoping for a software migration tool, or an import path available in Alfresco.
It sounds like a pretty horrific case of Vendor Lock-in. If I were in your place, I'd spend some serious time unpicking the Laserfiche file format with hex editors, and so on, see if I could figure out anything from the content of the file, and the hex representation of it. It might turn out that there's something standards-compliant buried inside an ugly dirty proprietary file.
It's probably against their terms and conditions, but if you don't shout too loudly about it, who gives a toss?
There has to be some way to get the data out of these files, but it's a matter of how dirty you're prepared to get.
