If you are using our Power Scripts for Jira app (the SIL provider) you may have noticed that there is sil.aliases file in the Kepler folder of your Jira Home folder. This file maps the custom fields into a more easy readable names that can be used in the SIL scripts. KIWI transfers this file from an instance of Jira to another system.
The export operation encapsulates the entire file form the source server including the comment lines.
A successful import generates this file in the KIWI home folder with the name: <exported_workflow_name>_sil_<timestamp>.aliases , where <timestamp> represents the date when the file is generated, in the yyyyMMddHHmm format. For instance, the Workflowfortest_sil_201310071330.aliases file is the sil.aliases file generated when importing the workflow Workflowfortest on 07.10.2013 13:30). This file contains only those custom field aliases that were imported, re-mapped according to your .cfmap file and according to your screen selection. However the generated file <exported_workflow_name_sil>.aliases contains only the delta, for example what was changed by the current import process.
To merge your generated file in the sil.aliases launch the corresponding tool.
