Package Upgrades</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>Packages that are preinstalled using InterpretSIS must follow certain rules

while upgrading, as explained in the following sections: </p>

<section><title>Standard upgrade rules</title> <p>InterpretSIS supports the

following upgrade types: </p> <fig id="GUID-E97B0D4F-6B3A-5595-A0C2-B87C1457E80F">

</fig> <p>* The base SA and associated upgrades are removed ** The base SA

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.
