ESS/MSS Upgrade to 2004s SP11

23 Views

Hi ,

Currently we are on 2004s SP9 and intend to move to SP11.

I have a couple of questions here. WE are using mySAP ERP BP for ESS and MSS with SP 6 ( i.e compatible with 2004s SP9). We made lot of changes to some web dynpro code and went live 2 months back. Now as part of the upgrade if the basis team installs SP8 for BP's ESS and MSS(2004s SP11) through JSPM/SDM on the EP J2EE engine, will it override all the custom code that we have done? I surely guess so. In that case do we not install SP8 for BP's ESS and MSS through JSPM but rather follow the 4 track methodology for upgrades and upgrade ESS MSS through NWDI rather than JSPM?

I am sorry if i had confused you guys, this is the first time we doing the upgrade after go-live .. hence the basic doubts.

Any note or reference for upgrade startegy will be pretty useful

thanks alot in advance

regards
