What the impcat to my application if i upgrade 10.0 to 11

[sohochaser]

Hi All,

I have a portable c++ application(binary size: 800M) run under solaris, aix,hp, Linux and SUSE 10 SP2(SLE-10-x86_64-SP2).

We have certificate that the application works well under Suse 10 SP2. Now we try to support SLES 11? Here are my questions:

1. What the main impact of the upgrade?
2. Is there any guide of the upgrade?
3. Is there some compatibility issue?

Any one get ideas?
Thanks,
Allen
