All software has bugs or ‘unexpected features’ and beta software often has even more; expect problems and plan accordingly. On your test system, install digKam 5.9.0 (or whatever version you’re currently using), copy over digikamrc from your working installation and edit it to refer to the 6.0.0 database. You’ve now ‘cloned’ your 5.9.0 install and database so test it works and fix any problems before proceeding. You can then upgrade your test 5.9.0 install to 6.0.0. as this tests the software upgrade process for your setup.<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>After upgrading your test install to 6.0.0 you can finally try it. What can you expect? Your anti-virus software may object to unsigned programs so be prepared to deal with this. From my observations, the first time digKam 6.0.0 runs against a 5.9.0 database, it takes a loooooooong time to startup which, given that there’s a database upgrade, should be expected. Go and have a cup of tea/coffee and give it time to finish! In addition, even when digicam 6.0.0 appears ‘ready to use’ there are background activities still in running so check both digicam itself (task manager on Windows) and the database server (top on Linux) are idle before trying to use digicam seriously. Depending on your hardware and database size, this may take a couple of hours.<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>I’ve used this process to test all the recent betas without impacting my working 5.9.0 setup and, encouragingly, have not encountered any major problems.<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>If you’re not wanting to test the beta releases, life is a little simpler so ….<o:p></o:p></p><ol style='margin-top:0cm' start=1 type=1><li class=MsoListParagraph style='margin-left:18.0pt;mso-list:l1 level1 lfo3'>Backup your current database, pictures and digikamrc to two different places e.g. NAS and offline disk – anything important should be stored in three different places<o:p></o:p></li><li class=MsoListParagraph style='margin-left:18.0pt;mso-list:l1 level1 lfo3'>Install the digiKam 6.0.0 software package and run it<o:p></o:p></li><li class=MsoListParagraph style='margin-left:18.0pt;mso-list:l1 level1 lfo3'>Go for a tea/coffee and check it’s finished.
