Hi Guys,

We are in phase of deploying Win 7 allover the orgn, basically we have many kinds of appls resonse differently to the OSes, althought we tested many of them for the compatibility with Win7 and got Green flag. but still not daring to deploy in production. please suggest how we can ensure that won't face incidents/problems due to this change.
Note: we have hundreds of appls responds differently to diffrent OSes.

This is a significant change if it is going to be organization wide...

You will need to ensure proper impact analysis and will need to call upon experts from each application to test their applications impact if loaded on Windows 7... Once you have signoff from all the critical applications owners (post testing) - you can then proceed with the implementation to production environment on a phased basis week on week to allow the deployment and still to see the impact of it on a phased manner...


hope this gives a direction to proceed

I think you have a bigger problem than Windows 7

First, windows 7 is a desktop / laptop o/s. It is NOT a server o/s. That would be windows 200x etc

Second, do you have a standard build for the desktop and the laptops ?
If so, then do all of your internal apps work with the current standard build laptop

if NOT, do that first before you even consider Windows 7

That would be the first project

i would add more but then this would go beyond free advice

true John... I overlooked and mis understood this.... Sorry

Your solution sounded all fine

So use a standard build... test applications against these standard build

and deploy Win 7 OS in batches to ensure no big mishap

Thanks for all your suggestions,
as I mentioned, the problem is we have 'n' number of appls specially designed for IT manufacturing and PLMS developments, our client there is still using Win 2K for developing there frameworks (platform for our development) causing many conflicts with day to day upgrades to our deliverables.
here, the users are demanding Win 7 as it is graphic oriented and helpful for there designing work in CATIA or so.
We have 'N' number of environments and it's very difficult to build each of them and then test it, I understand this is the best possible option but can you suggest another one?

What do you want ?

Do you want an detailed implementation / project plan on how to take your desktop / laptop environment from what it is to Wintel7

Windows 7 - for the normal business user does not provide any more functionality than XP or win2k has. It needs more RAM 4 GB at a minimum and the latest CPU style to make it work right

So if you are going to put Windows 7 in, you will most likely have to replace desktops and laptops to meet the minimum requirements for the O/S

if this is a a Domain'ed environment, you will most likely have to upgrade the backbone architecture - win2003 server and higher - in order to manage these

The fact that some group wants windows 7 is immaterial
