With Precise 9.7.0, the JRE packaged with the product changes from JRE 6 to JRE 8, and the GUI Tomcat changes from Tomcat 6 to Tomcat 8. For Precise 9.6.x to be successfully upgraded to 9.7.0, you must verify that no process outside of Precise is locking the following paths:

• <precise-root>/java/JRE
• <precise-root>/products/gui/website

The following tools can assist you in this process:

• Windows platform: Windows SysInternals (handle.exe)
  This command line tool can be downloaded from:
  https://technet.microsoft.com/en-us/sysinternals/handle.aspx.
  Usage: handle.exe <path-to-folder>
  For help: handle.exe help
  Verify that the output does not list any non-Precise process holding a handle to the above mentioned Precise folders.

• UNIX platform: lsof
  lsof comes preinstalled on many UNIX systems. If your system does not have this tool, you please install it.
  Usage: lsof <path-to-folder>
  For help :lsof –h

Verify that the output does not list any non-Precise process holding a handle to the above mentioned Precise folders.
