I have to do a migration of PORTAL 6 6.20 to PORTAL 6 NW04 (WAS 6.40). I already did.
For that I have two machines. I've installed one CI and DI. But one of the problems is:
There are two URL's with differents port numbers. To solve this problem does the best solution is Web Dispatcher? If it is, do i have to have another hardware device or software for Load Balance? Or only two machine with one IP address each? Could I install in the same two machines?
Second: For HA - I've read many things that make me clear that the best solution for HA is install SCS in other machine. But I've already installed the CI with SCS. Could I move it - SCS (unistall from CI and install in other machine) changing the appointment or do I have to reinstall all environment?
Could you help me with this doubts?
