installing sql server 2005 alongside analysis server 2000

analysis services 2000 work fine on my machine so i dont want to go near them ,but i do want to upgrade sql server 2000 to 2005. can i have sql server 2005 and analysis services 2000 work side by side on a server?Yes - you can do it. The AS2005 will have to be installed as a named instance, because you cannot have two default instances on the same machine and AS2000 didn't support multiinstancing.
