Can I update mondrian version to 3.7 in BI server 4.8?

Hi everyone!

I'm using BI server 4.8 and saiku analytics in an enterprise in Venezuela. I tried to update to bi server 5 but the users resisted to UI changes, so I have to keep using 4.8 for a while.

I wish to update Mondrian to 3.7 but I don't know if it's possible and how to do it in BI server 4.8...

I'll appreciate any kind of help or advice :)

Thanks in advance!
