+<concept id="GUID-CFC21A23-0299-4420-BB60-584D10C8913A" xml:lang="en"><title>Updating
+the platform UID</title><shortdesc>This topic describes how to update the platform UID.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>When porting applications from S60 5th Edition to Symbian^3, you can include
+the Symbian^3 platform UID in your application's <codeph>.pkg</codeph> file
+and create a new <codeph>.sis</codeph> installation package using the modified <codeph>.pkg</codeph> file.
+The platform UID for Symbian^3 is <codeph>0x20022E6D</codeph>.</p>
+<note> If you do not include the Symbian^3 platform UID in your package file
+and create a new <codeph>.sis</codeph> installation package, the user gets
+a compatibility warning when installing the application. The warning may result
+in the user canceling the installation.</note>
+<p>To add Symbian^3 UID, include the following line in the <codeph>.pkg</codeph> file
+of your application:</p>
+<codeblock xml:space="preserve">[0x20022E6D], 0, 0, 0, {"Series60ProductID"}</codeblock>
+<p>If you have verified that the same binary can be used on multiple Symbian
+platform releases, you can include platform UIDs for multiple Symbian platform
+releases in your package file as illustrated by the following example:</p>
+<codeblock xml:space="preserve">;Supports S60 3.0
+[0x101F7961], 0, 0, 0, {"Series60ProductID"}
+
+;Supports S60 5th Edition
+[0x1028315F], 0, 0, 0, {"Series60ProductID"}
+
+;Supports Symbian^3
+[0x20022E6D], 0, 0, 0, {"Series60ProductID"}
+</codeblock>
+<p>For more information and a list of the platform UIDs used in earlier Symbian
+platform releases, see <xref href="GUID-FBA816FE-E188-4A40-9B9B-D47F7D3390AE.dita">Platform
+UID</xref>.</p>
