Good morning, in my office we have a document management system that uses the lucene and the pdfbox. The Version of lucene is 2.0.0, pdfbox is the Version 0.7.3. Now I would like lucene update to a newer version, but I can not find sufficient assistance in the community. What do I do best? Taking small steps to update or directly to a current version such as 5.4.0? Is there a description / instructions for Lucene to a newer version to migrate? Thanks for your help. Best regards Mit freundlichen Grüßen Maik Grabenhorst [Logo_neu] [cid:image001.png@01D11BB1.0DA762D0][cid:image002.jpg@01D11BB1.0DA762D0] Military Support Germany - Airbus Group ESPZB - IT & Tools Tel.: +49 (0) 906 - 71 8031 Mobil: +49 (0) 151 - 652 319 08 e-Mail: AIRBUS HELICOPTERS DEUTSCHLAND GmbH Sitz der Gesellschaft / Registered Office: Donauwörth Registergericht / Registration Court: Amtsgericht Augsburg HRB 16508 Vorsitzender des Aufsichtsrates / Chairman of the Supervisory Board: Guillaume Faury Geschäftsführung / Board of Management: Dr. Wolfgang Schoder, Vorsitzender / CEO; Johannes Kleidorfer; Dr. Klaus Przemeck; Martin Schübel; Stefan Thomé The information in this e-mail is confidential.
