Right know we are starting our CS implantation, so we have CS 10.0 in Solaris Operating System, the project include some developments like Web Services (for document creation in CS and other specific necessities) and Personalized Web Applications that consume those Web Services. Also we plan to migrate to CS 10.5 the next year, so What's the best option for us to develop now and minimize overload when we'll migrate our platform to the last version of CS?
