We are using SAP 4.7 Ext2 in Solaris 9 OS. My client is planning to upgrade Solaris 10 from existing Solaris 09. I suggested to perform a homogeneous system copy. But the client does not want to go for it. His proposed strategy is to upgrade Solaris 9 to Solaris 10 keeping the SAP file system intact. Is it feasible to upgrade the OS like this without performing a homogeneous system copy? If it is possible then what are the precautions have to be taken and what OS level configurations have to be chenged after the upgradation. Kindly acknoweledge me about it as I am naive to this.
Thanks in advance,
