Exactly, that's what you have to do.

If you have a spare system, you could try to make a complete backup of one server and do the upgrades there, so
- copy all data to spare system
- upgrade to RH5
- start Domino and test it (locally, don't replicate!)
- shut down Domino, and upgrade to R8.5.1
- test the complete server

The documentation I sent you the link for should contain some advice about how to upgrade a server park and clusters without disrupting mail handling etc. Check that.

Lotus Domino 8.5.1 requires Redhat Linux 5, so I need to upgrade OS before upgrade Lotus.
Can I upgrade one server first for testing before upgrade all system?  
Free Tool: ZipGrep

ZipGrep is a utility that can list and search zip (.war, .ear, .jar, etc) archives for text patterns, without the need to extract the archive's contents.

   Hi there vinhbt,,,

Firstly,,, you mentioned that you have a " redhat AS4 "OS which  couldnt really be found  in the Lotus Notes domino 8.5.1 system requirement :

Secondly, if you really would like to go any Lotus notes Upgrade wither now or in the future the best thing to be done is to refer to the " Upgrade Center " and in your case specificlly " Upgrade Central: Planning your upgrade to Notes and Domino 8.5.1" is the best thing

Best Wishes
Personally, I highly recommend you start with a testing server then move to the least effecting production server . In other words, a production server which will not effect much users or other servers if it has an issue .

I tested upgrade successfully with new server. But user database did not upgrade, it still uses old tempate. How to upgrade user database to uses new template of domino 8.5.1?
Sjef BosmanGroupware ConsultantCommented:
Either ask the users to do the upgrade themselves (File/Application/Replace Design), or upgrade all databases in one action, on the server (read carefully):
