Dear Managers,

At last finally I could able upgrade my OS from 2.6 to 8. I thank you every 
body who responded with their valuable hints. I don't want any other Sys 
Admin to be panic infuture, as there is specific document talks about the 
problem solution.

My sincere thanks to Kevin, Robert and Justin for their time and hints, 
which led me into right direction. I also took help from Sun Support 
ONLINE...after which they directed me to do the following:

I. /etc/vfstab

- Comment out all NFS entries.
- Check for multiple swap entries. Comment out all except for one simple
  disk based swap partition.
- Comment out all data (or non-O.S.) partitions.
- Make sure root partition is on slice 0
- Having entire O.S. in slice 0 is OK.
- Make sure there are no /dev/md/ devices. If any exist, see DISKSUITE 
section
below
- Make sure there are no /dev/vx/ devices. If any exist, see Volume Manager
  section below

II. FSCK

- Make sure to fsck all devices.
- Boot from cdrom and run fsck by hand to fix problems prior to upgrade.

III. LINKS

- Watch out for links that use absolute paths. Upgrade will overwrite links
  that it can't reference. This could cause the partition to run out of
  disk space.
- Remove packages that will make changes to automounted directories.
- If symbolic links exist from /var/sadm, either restore the files on
  the /var partition or do a full install.

V. /var

- Make sure /var is under root or a separate partition. /var should not be
  a link.
- /var/sadm must not be a link or a separate partition.
   Must be directly under /var.
- If symbolic links exist from /var/sadm, either restore the files on
  the /var partition or do a full install.
- Run upgrade.chk to make sure /var/sadm/install/contents is not corrupt.
- Make sure /var/sadm/softinfo/INST_RELEASE exists and the contents look 
like;
  OS=Solaris
  VERSION=2.3
  REV=0

Thanks to all responded, I appreciate your time.
