Objective - Sharepoint 2013 (only specific content - 1 site) migrate to Sharepoint 2016 - only wish to migrate single site collection - easiest method?
Plan is to migrate for testing ahead of live cutover (so at this stage not keen to use DB attach method if possible)
New to company so no IT history with how previous sites setup etc This seems to be far more complex than it should be, not that familiar with SP. Have tried the DB backup however this contains multiple sites, many no longer active or valid and dating back to SP 2007 - so full of rubbish and non compatible items/features
Tried a granular backup of site, on SP2016 cannot restore this as does not see this file (copied locally, tried multiple file ext's))
Any and all suggestions welcome!
