This is the component we are using in the version 1.0 msi which drops the
database on uninstallation. And we want to prevent this when we upgrade from
this to the newer version.
<Component Id="SetupSqlDataBase" Guid="SomeGuid">
<SqlDatabase Id="CreateDatabase" Server="(local)\[SQL_DB_INSTANCE]"
Database="[SQL_DB_NAME]" CreateOnInstall="yes" CreateOnReinstall="yes">
<SqlScript Id="sqlScript" BinaryKey="sqlScript" ExecuteOnInstall="yes"
ExecuteOnUninstall="no" ContinueOnError="yes" Sequence="1"
ExecuteOnReInstall="yes"></SqlScript>
</SqlDatabase>
<SqlDatabase Id="DropDatabase" Server="(local)\[SQL_DB_INSTANCE]"
Database="[SQL_DB_NAME]" CreateOnInstall="no" DropOnUninstall="yes"
CreateOnReinstall="no" ContinueOnError="yes" />
</Component>
Thanks

Subject: [WiX-users] Partial uninstall of previous version
HI All,
I ‘m a new user of wix and trying to figure out a good design to solve my
problem.
I’ve one version (say 1.0 ) of my product installed on my system and I want to
upgrade it to 2.0. After the installation of 2.0, I want to partially uninstall
the 1.0.
By partial uninstall I mean remove/unregister files but keep the database. The
older MSI on uninstall drops the database which is a problem for us.
Does their exist a good solution for this?
One solution I could think of is to take the DB backup and then Install 2.0,
call RemoveExistingProducts and populate DB. But I guess this is inefficient.
Thanks
Sandeep
