Pulse 2 Secure Agent 1.1.x to 1.2.x upgrade instructions

The installer performs three operations on the target computer :

1. stop and delete any Cygwin OpenSSH service detected,
2. copy the Cygwin tree,
3. configure the client :
   1. generate an OpenSSH key,
   2. set-up and start the OpenSSH service.

If the installer is run using the "/UPDATE" flag, steps 1 and 3 are not performed.

It is recommended to use the "/UPDATE" flag for updates by deployment.

Warning : if the "/D" flag was used during install (or if you do specified an alternate installation folder), don't forget to specify it anew during the update !
