Hi SoniaSinha,
where do you wanna see a different name?
In BSM -> Admin -> SAM -> Summary, as on my screenshot
where the Sitecope instances are listed under Summary?
In that case you need to change the Display Name by right-click on the Instance and then Edit SiteScope, under Main Settings -> Display Name.
If you are talking about another area in BSM, plesase specify.
Greetings
Siggi
