Here is my statics during Ubuntu 9.10 To Ubuntu 10.04 LTS (RC Release) upgrade process.

I started upgrade early in the morning in IST time zone with 8 MBPS Broadband Line. I was already running Ubutnu 9.10 with latest updates. During upgrade process, 1574 package was upgraded, 242 was new and 27 packages was removed. It took 45 minutes to download 1064 MB of data. Total upgrade time from Start to Reboot was around 3 hours on my Intel Dual Core machine with 4 GB Ram, i did Bath, Breakfast and checkout during this time. Last upgrade was of Ubuntu 9.04 under 40 Degree Celsius temperature @ Ahmedabad, this time i was in BLR with 20 degree Celsius temperature, Actually my laptop has heat problem, so this parameter was concerned for me.

After successful reboot, you will notice purple Ubuntu Boot Splash. If everything goes fine it should boot perfect, which happened in my case, you may have to change themes  and your existing desktop to give complete Ubuntu 10.04 LTS look.

I have also noticed 100% CPU utilization during “Cleaning Up” stage.

Observation:
If everything goes fine, your system will boot in newly upgraded Ubuntu 9.10 Beta with newly introduced Ubuntu xsplash base boot screen. I got the success. But I have found some problem in compiz (My compiz effect was running during upgrade process). My system was performing slowly. I have Nvidia GeForce Go 7400. I have simply remove the compiz using

sudo apt-get remove compiz*

Tip:
You may not see the new Desktop look of 9.10 beta, i would suggest to create new Desktop User and then login with that user to experience new look

Update:
Latest update of 9.10 (Beta) has solved my compiz problem with Nvidia card as i have written earlier. Before update i had:

-rw-r--r-- 1 root root   41192 2009-10-05 20:35 compiz_1%3a0.8.3+git20091005-0ubuntu5_all.deb
compiz_1%3a0.8.3+git20091005-0ubuntu5_all.deb

In today’s update:

-rw-r--r-- 1 root root   41418 2009-10-16 18:34 compiz_1%3a0.8.4-0ubuntu1_all.deb

Now compiz + Nvidia (Version 185) + Ubuntu 9.10 Beta (Upate on 2009-10-16) Rocks
