It is possible to have SC3, SC4 and SC5 installed on the same server/workstation. During installation You are asked about a windows service name, that name MUST be different for the 3 servers. In addition You should know that if you want all 3 servers running at the same time you need to have them running on different ports.



In addition to this you can have more than one set of data for each sc server. You just copy the DATA directory the number of times You want servers, rename them to something logic and change your sc.ini somewhat like this:



# data for normal sc5 system

path:C:\Program Files\ServiceCenter\DATA



# data for canned sc5 system

#path:C:\Program Files\ServiceCenter\DATAcanned



# data for sc5 system moved to db2

#path:C:\Program Files\ServiceCenter\DATAdb2

#sqldb:sc5

#sqllogin:*****/******



Then whenever You need to change to a different server stop the server, switch the path in the sc.ini and restart.
