Hi,

Is there no solution for the error (when upgrading V4 to V5): Cannot insert duplicate key in unique index '_id'. The duplicate value is '{"$numberLong":"1126889"}'. ?

Could you add some 'ignore error' switch, or 'drop duplicated item' option?

I have a similar problem when upgrading (using 5.0.20):

LiteDB.LiteException: Cannot insert duplicate key in unique index '_id'. The duplicate value is '"59803E0EF693557459A7BCA047C118F998256C06E4BF7A1C4880012FF97E47B2"'.
