Hi Snehal , There are two ways by which you can go for it,these are:- 1) From 8.O.M030 to 9.0 --> do a upgrade & then from 9.0 do an update to 9.1_MO10. 2) Do directly Upgrade from 8.OM030 to 9.1_MO10. Choice is yours how you want to approach. Also following are the points you may want to consider while doing this. 1) Make Windchill stable at 8.0M030.(Like you do in normal Upgrade) 2) Stop Windchill (all Method Servers , Server Managers & Windchill services on all master,slaves & replica nodes). 3) Take a backup of data base,aphelion & codebase. 4) Do upgrade or update which ever you want to use.
