I am getting ready to build a quick migration utility for a legacy Laserfiche 8.1 system.  The client is moving to a different ECM solution and has specific criteria for export format of documents and metadata. 

The migration utility will require PDF document export and access to template data.  I am going to stick with LFSO for this utility but was wondering if I should build the utility with an older version of the SDK (my earliest version is 8.2) or am I going to be OK with using a much more current SDK, say LFSO 9.1? 

My primary concern is running into any issues if I use a newer version of the SDK to connect to and export documents from a much older legacy repository.

Thoughts and recommendations?
