Hi,<br />
We have 2 Hub, 2 CAS , 2 Mailbox and 1 Public Folder server in my organisation.<br />
OS version <br />
CAS/HT/PF == Windows 2008 R2 Standard Edition<br />
Mailbox -== Windows 2008 R2 Enterprise Edition<br />
Exchange Version<br />
CAS/HT/PF == Standard Edition<br />
Mailbox = == Enterprise Edition<br />
All servers have SP2 without any RU . Build Number 14.2.247.5<br />
<br />
I am planning to upgrade them to SP3 RU11.<br />
I have few questions<br />
<br />
1) &nbsp;Is SP3 and RU11 is same of all Exchange version ( Standard/Enterprise) or is it different for different Editions?<br />
2) Can I do SP3 and RU11 update directly or do I need to update it first to any RU of SP2 first and then to SP3?<br />
3) Can I install SP3 UR11 directly or do I need to update first to any RU of SP3?<br />
3) Does RU11 for SP3 have all the fixes of previous updates or not?<br />
<br />
Thanks
