One thought... If your old (1.4.1) Solr index has all fields are 'stored' (stored="true" in schema.xml for field), then you can easily create a migration tool which would pick the data from 1.4.1 Solr instances and put it into 3.5.0.

Because indexing is really a huge costly process in our case because the data generated needs some calculations which takes lot of time. Else otherwise if there is any other tool which can update lucene indexes all by itself please do let me know.
