We have a fat client PB application installed on 200 machines that connects to an oracle 10g server. IT is very hard to maintain.
We would like to do one of the following:
1. Migrate from 2-tier client/server (fat client) to 3-tier (thin client) architecture
2. Migration from 2-tier client server to n-tier web architecture.
What kind of work is involved in Option 1. Is it difficult to do or just a matter of copying the executables to an application server and all users run it from there. Do we need a special application server for that?
Would it be more difficult to go to a web architecture. DO we need to recode the whole application in some other language or Sybase offers tools to allow you to do this.
Is there any good reference books on doing the above migrations
