This document describes the user interaction for migrating old symptom databases (WAS format) to the new symptom database format.

Scenario:
The user had previously installed TPTP 4.0 and had created a runtime workspace with one or more symptom databases and one or more analysis engines.
The user now decides to move to a higher version of TPTP, and he installs TPTP 4.1, which contains the new symptom database format.

Once he moves to TPTP 4.1, the user expectation is that his old runtime workspace will have exactly the same functionality as it had before, meaning that he would be able to view/update the xmi symptom database (lets call it sdb.sdbxmi) and use the analysis engine implementation to analyze log files.
The migration tool should allow the user to perform these tasks.

The user chooses to edit the existing sdb.sdbxmi file

To do that, he selects the sdb.sdbxmi file in the Eclipse navigator and double clicks on the file. At this point, the default editor should open on the selected resource.

A message box is displayed, informing the user that the selected xmi file is an old symptom format. The user is asked if he wants to migrate the file to the new format.
If the user answers yes, the migration starts and a new xmi file with extension symptom is created. This file, sdb.symptom, contains the migrated symptom database file.
The sdb.symptom file is selected in the navigator and before the editor opens, the user is asked is he wants to remove the old symptom file from the workspace. On yes, the old file, sdb.sdbxmi,  is removed.

The editor opens on the new xmi file ( sdb.symptom ) and the user can view/update the content.

The use wants to analyze log files using his analysis engine and sdb.sdbxmi symptom database file.

The user opens a log file into the log view and selects the Analyze action. The available Analyze engine implementations should be visible in the popup action ( ie the old analysis engine implemented by the user using the old symptom database format and any other analysis engines, based on the old or the new symptom database format )

If the user selects to analyze the log using an analysis engine that only understands old symptom database formats, only symptom database in the old WAS format ( extension sdbxmi ) will be used for analysis, and any other (extension symptom)will be simply ignored.

If the user selects an analysis engine based on the new symptom database format, old symptom database that were chosen by the user to be used for analysis will be first migrated under the cover to the new format and next will be used in analysis.
