SVN: 38718

installation/resource/installer/bin/upgrade-eln-v3.sh

+#!/bin/bash
+# Upgrades openbis ELN-LIMS. 
+# Asumes that the eln-lims tarball is on the 'servers' directory 
+# Assumes that core-plugins are installed in the 'servers' directory on the same level as this script parent directory
+
+##
+## Upgrade script algorithm explained
+##
+
+#-- If current installation don't exists return with message, no eln-lims installation found, do a normal first installation
+
+#-- If installation exists
+#-- Check if current installation is a minimum master data installation
+#-- Backup etc folder (skip if etc folder don't exist)
+#-- Remove eln-lims folder
+#-- Uncompress eln-lims tarball into the core-plugins folder
+#-- If last installation was minimum master data installation, remove extra eln-lims master data script (skip if wasn't)
+#-- Restore etc folder from backup (skip if backup don't exist)
