Hi.
We have current currently several SQL 2005 Enterprise instances in a 2-node Windows cluster.
We plan to install SQL 2008 Enterprise on the same cluster.
Are there any limitations, conflicts on having clustered SQL 2005 & SQL 2008 instances sharing the same servers ?
Are any pitfalls ?
Thank you for your advice.

As long as you set the max memory for each instance so that you are not consuming all of the available memory and you have enough resources to support multiple instances, there really shouldn't be any problems.

Hi Serge,
We can very well install Different Editions/versions of SQL Server on a single machine or cluster machine. Like in our case SQL 2005 & SQL 2008. Now the thing that we need to take care are:
We should have enough memory to support both of the versions and
best is to Cap Max/Min Server memory for both of the instances
and leave good amount of memory for OS as well.
We should have good amount of resources on the server so that it can
handle both of the editions.

I assume you would just create a separate folder for the 2008 version? Anything tricky about this install (i.e., pitfalls to watch for)?
