I was struggling with the same issue and because I'm fairly new to WIX
and MSI in general I was not able to find a 'clean' Solution.
What I have so far is the following, I consider this a 'Workaround' :
<!-- Support Upgrading the Product -->
<Upgrade Id="{B0FB80ED-249E-4946-87A2-08A5BCA36E7E}">
<UpgradeVersion Minimum="$(var.Version)"
OnlyDetect="yes" Property="NEWERVERSIONDETECTED" />
<UpgradeVersion Minimum="0.0.0"
Maximum="$(var.Version)" IncludeMinimum="yes"
IncludeMaximum="no"
Property="OLDERVERSIONBEINGUPGRADED" />
</Upgrade>
<Property Id="OLDERVERSIONBEINGUPGRADED" Secure="yes" />
<!-- Action to save and Restore the Config-File on reinstall
-->
<!-- We're using CAQuietExec to prevent DOS-Boxes from
popping up -->
<CustomAction Id="SetQtCmdLineCopy" Property="QtExecCmdLine"
Value=""[SystemFolder]cmd.exe" /c copy
"[INSTALLDIR]MyApp.exe.config"
"[INSTALLDIR]config.bak"" />
<CustomAction Id="QtCmdCopy" BinaryKey="WixCA"
DllEntry="CAQuietExec" Execute="immediate" />
<CustomAction Id="SetQtCmdLineRestore"
Property="QtCmdRestore" Value=""[SystemFolder]cmd.exe" /c move
/Y "[INSTALLDIR]config.bak"
"[INSTALLDIR]MyApp.exe.config"" />
<CustomAction Id="QtCmdRestore" Execute="commit"
BinaryKey="WixCA" DllEntry="CAQuietExec" />
<!-- These actions will run only for a major upgrade -->
<InstallExecuteSequence>
<Custom Action="SetQtCmdLineCopy"
After="InstallInitialize"> NOT (OLDERVERSIONBEINGUPGRADED = "")</Custom>
<Custom Action="QtCmdCopy"
After="SetQtCmdLineCopy">NOT (OLDERVERSIONBEINGUPGRADED = "")</Custom>
<Custom Action="SetQtCmdLineRestore"
Before="InstallFinalize">NOT (OLDERVERSIONBEINGUPGRADED = "")</Custom>
<Custom Action="QtCmdRestore"
After="SetQtCmdLineRestore">NOT (OLDERVERSIONBEINGUPGRADED =
"")</Custom>
</InstallExecuteSequence>
This basically copies the File 'MyApp.exe.config' to 'config.bak' before
the old Version is removed and after the new Version is installed, the
File is moved back to it's original Filename (thus the .bak File is
removed)
This works fairly well but I'm still wondering if there's a more
intuitive and cleaner approach to keep configuration settings when
performing a major upgrade ?
(No, I don't want to use the Registry)
Btw, I'm using WIX 3.0.3815.0

That doesn't work. A component's condition applies to installation. So
once a component is installed, you can't conditionally uninstall it when
you remove the entire application, which happens during the major
upgrade. Then you can choose not to re-install the component on a
condition, but the configuration files will be removed by then.
As Markus Kuehni wrote in his previous post, MSI keeps doing the "right
thing", which is to keep track of files and never leave anything behind.
I think an extended file copy/move/delete would be a nice and simple WIX
extension invoking the custom action and one could specify a condition
on that.

I tried, but using FileId or putting FileCopy under a File will delete
my file on uninstall and not using FileId silently did absolutely
nothing and didn't show anything in the log. Basically I couldn't get it
to work. Maybe a bug?
Hmm...Maybe another component with the right condition?
