Whether or not, and when, you should upgrade is dependent on your environment. If you are having service impacting or performance issues due to one of the defects resolved in this release, then that would push you to move to 4.1(7) rather than later. Otherwise, a rule of thumb I always used while working in Advanced Services was to wait ~6 weeks after a release to allow for enough field expsoure and to give you time to perform internal lab validation and testing.
For a graceful termination of existing TCP flows optimized by WAAS, we recommend that you disable WCCP on the WAE first, as described in Step 1 of this procedure. Then wait until the graceful timer counts down, during which period no new connections are redirected to the WAE and the existing connections are allowed to gracefully terminate. Upon completion of the countdown timer, all existing connections are terminated.
P.S. if this answers your questions, please mark it as answered with a 5.
The command line method asks me to log into each router and shut down wccp while the CM GUI method does not. Does the CM GUI method do something to make it clean without shutting down wccp on the routers?
There really isn't much difference between the two methods. The upgrade process using the Central Manager doesn't do anything to gracefully shut down WCCP and upgrade the device. Two benefits you do get by upgrading through the Central Manager are:
- The ability to upgrade an entire device group at once
- The ability to auto reload a device once the software has been downloaded and installed
