I am doing a major upgrade of a service application.
I managed to preserve the service information by removing
InstallServices and DeleteServices during UPGRADINGPRODUCTCODE and
OLDERVERSIONBEINGDETECTED. This has one drawback that I can't add a new
service to the application any more during a major upgrade. I can live
with that for now.
<InstallExecuteSequence>
<FindRelatedProducts Before="LaunchConditions" />
<RemoveExistingProducts After="InstallValidate" />
<InstallServices>NOT OLDERVERSIONBEINGUPGRADED</InstallServices>
<DeleteServices>(NOT OLDERVERSIONBEINGUPGRADED) AND (NOT
UPGRADINGPRODUCTCODE)</DeleteServices>
</InstallExecuteSequence>
I have a configuration file config/Config.xml, that I managed to
preserve by copying a Config_Original.xml to Config.xml at clean install
only (never install Config.xml). I couldn't get this to work with
CopyFile - it never ran without a FileId or forced a file to be
uninstalled otherwise. I did it with a custom action, but that's
admitting failure :)
<CustomAction Id="CopyConfigXml" Directory="config"
ExeCommand='cmd.exe /Q /C "copy Config_Original.xml Config.xml"'
Return="check" Execute="deferred" />
<InstallExecuteSequence>
<Custom Action="CopyConfigXml" Before="StartServices">(NOT Installed)
AND (NOT OLDERVERSIONBEINGUPGRADED)</Custom>
</InstallExecuteSequence>
Question: how do I do the config.xml file part cleanly and maybe a
better way for the service part?
Thx
