First, thank you to Dr. Blinn, Mark Vallee, John Farmer and Alex Gorbachev
for their responses.
In short I will wait until I get to 5.1 to update the products listed once I
have verified they in fact require an upgrade also.  
One comment I would like to pass along is :
"Do not use the Advanced file system utilities until I upgrade the product,
as it may cause corruption with my existing file domains."
As this is my first tru64 upgrade, I would like to thank the list, as I have
been watching the various summaries pass through
my mail box discussing the upgrade process and what and "what not" to do.

Original Question
I am on my way to upgrading to 5.1 and have successfully upgraded to 4.0g.
In the update log, I have the following list of layered products that may
need re-installation.
        Advanced File System Advanced Utilities 
        CABASE 
        CCATBASE 
        CT5 Reader Tool 
        DSNlink V3.0 for Compaq Tru64 UNIX 
        Legato NetWorker 
        Perl Language V5.004_04 
        StorageWorks SWXCR Utility for Digital UNIX V1.2.3 
        StorageWorks RAID Array 200 Management Utility V1.2.1 
        UniCensus 
        Compaq WEBES Common Components V2.1 
        Web-based Enterprise Service 
Can I wait until I get to 5.1 to do the re-installation or should I do it at
the current rev (4.0g) ??
The ones I am most concerned about are the 
ADVFS Advanced Utilities
Storageworks utilityies
Thank You
Darren
