+is removed prior to the installation of the SA upgrade. </p> <p>InterpretSIS
+returns an error if the rules are violated during an upgrade. It supports
+variants of file names and usage of wildcards for Stub SIS files. </p> </section>
+<section><title>Non-removable package upgrade rules</title> <p>The following
+table summarises the rules that apply when performing patch upgrade, partial
+upgrade or replacement of <i>non-removable</i> packages installed using <codeph>InterpretSIS</codeph>.
+The general rule is that a removable package cannot be made non-removable,
+and a non-removable package cannot be made removable. </p> <fig id="GUID-20A6F1E5-45DC-5AC0-92F2-181A5AFB77F0">

+</fig> <p>* If the partial upgrade modifies files in the <codeph>SP</codeph>,
+the <codeph>PU(NR)</codeph> is modified when the <codeph>SP</codeph> is removed. </p> <p>**
+The original <codeph>PA</codeph> is removed, including the private directory,
+before upgrading. </p><p><b>Notes:</b></p><ul>
+<li><p><codeph>NR</codeph> upgrades are performed to the same drive as the
+original package. </p></li>
+<li><p><codeph>NR </codeph>upgrades or patches delivered on preinstalled media
+cards are rejected as invalid. Any invalid upgrade generates a <codeph>KErrInvalidUpgrade</codeph> error. </p></li>
+<li><p>Back-up and restore is not functional for preinstalled SIS files that
+are in the system drive. </p></li>
+<li><p>Preinstalled SIS files that are in the system drive can be uninstalled
+if <codeph>DeletePreinstalledFilesOnUninstall</codeph> is set in <filepath>swipolicy.ini</filepath> file.
