Hi Devendra
   You cannot deploy a newer version of an application when the older one still exists on the client. But you have mentioned that only few minor changes have been done to the application. For example let me assume that you have changed some code which was included in the jar file of the applicaiton.  This jar file always resides in the WEB-INF/lib folder to the applicaiton.  You just want to replace this jar file in the older application instead of deleting the application completely.  So the solution is to do this is to create a client installer archive which is nothing but an addon.  Please refer to the following documention about the <b><i>Client Installer</i></b> http://aiokeh.wdf.sap.corp:50000/SAPIKS2/contentShow.sap?_SCLASS=IWB_STRUCT&_SLOIO=6B5332E9145D0E469F134F7E7E04A34D&TMP_IWB_TASK=PREVIEW2&RELEASE=667&LANGUAGE=EN&_SEQNUM=144&_LOIO=43250E67B6140B25E10000000A1553F6&_CLASS=IWB_EXTHLP
or an alternate link is http://help.sap.com/saphelp_nw04/helpdata/en/3a/b834418b718739e10000000a1550b0/frameset.htm or even refer to the MI Installation Guide.
Once you have referred to the documentation you would know how to create a install.xml file and what are the tags contained in them.  Please make sure the MANIFEST.MF file contains an entry called <i><b>PatchArchive:X</b></i>. A sample xml for this problem would look like this.
<?xml version="1.0" encoding="UTF-8" ?>
<ARCHIVE name="Upgrade Application" description="Installer" uimode="full">
<PACKAGE name="MI25" description="New Jar file for application">
<TASK name="Delete old files">
<DELETE targetfolder="%MI_HOME%/webapps/your app name/WEB-INF/lib" pattern="**" mi_running="false" />
</TASK>
<TASK name="Add new files">
<COPY source="/app/" pattern="NewApp.jar" target="%MI_HOME%/webapps/your app name/WEB-INF/lib" mi_running="false" />
</TASK>
</PACKAGE>
</ARCHIVE>
If you create the xml correctly, this will definitely solve your problem
