We are using Plesk 6 for Linux where it has the support of Tomcat Verstion 4.x but previously we manualy installed the 3.x version of Tomcat in our servers directly without using Plesk and we have given JSP support for the clients now we would like to use the tomcat current version with the use of Plesk. Kindly advice how should we remove the pervious version which is manually installed in the server if we remove it will the clients who are already given tom cat support will get affected what is the alternative Kindly advice

Maybe post in the Plesk forum??
