Hi
I assume your management is 81.00 (since in 80.40 the install package shall be applicable for HF/Jumbo only and not for version upgrade)
Hope this answers all three questions you asked - if not, please let me know
Also will appreciate feedback on the experience you had using these APIs (boazo@checkpoint.com)
Thanks
Boaz
The best practice is simply not to use these parameters as the default values are the best - install the first member, perform connection sync or activate the MVC (depends on the target version - we know which methodology to use) and then failover and second member installation.
