There haven't been updates to Tomcat 6 for over a year; subsequent fixes for known security holes and other issues have been applied to current levels, but none of those will ever be retrofitted to Tomcat 6 (and 7, in the not too distant future). 8.5 or 9.0 are the only sensible choices. > Nevertheless.. is there some official documents on migrating to 8.5? Due to the age of where you're starting from (over 12 years old), you're not going to find anything specific for that level to a current one. What you can do is read all of the Migration Guides linked from here: http://tomcat.apache.org/migration.html and get a sense of the changes needed for your webapp configurations. You may well need to update JVM versions as well; if the one you're using is also 12 years old, it's scary dangerous. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
