SAP Service accounts password change

Hi,

We are almost yet to golive. We have implemented ECC6.0(ABAP+JAVA),BI7.0,EP7.0 . During installations network team has assigned temparary password to <sid>adm,SAPService<sid> for all dev,qa, prod systems.

Now as per security reasons client wanted to change all <sid>adm,Service<sid>password before go live.

Once network team change the passwords , where all i can go and reassign.So that it will replicate to all the entries.

Should <sid>adm,SAPService<sid> require same password or can be different?

OS : Windows2003

Database: MSSQL2005

but as per my knowledge, we have to change in services only.Please suggest if you have any thoghts and experianced on this scenario
