I want to upgrade from 4.1 SP3 to 4.2 SP4 on the same environment.
Also want to upgrade BODS from 4.2 SP3 to 4.2 SP 9 because of comparability with BI Platform 4.2 sp4.
So , i'll take back up of Connections, Universe and Reports.
a. Do i need to uninstall existing BO 4.1 SP3 Before to start with Upgradation and Do i need to use existing Port no. (Only CMS Port or All)
b. Which services i need to stop while up gradation and While taking CMS and Audit database backup?
c. Please suggest me what precautions and Procedure i need to follow?
I have got the following link but apart from this link if any would be helpful for me.
Thanks in advance.
