I got the solutions. You can use the reader extension server as a trial version.
The Adobe LiveCycle Reader Extension ES3 is fully comatible with the Adobe LiveCycle ES2 service pack.
Best of Luck, Developers.
This thread is very confusing to me. If you have ES2 with and a service pack installed you can upgrade to ES3 without issue. The trial version and purchased version of the software are identical from a technology perspective the difference is in the EULA where the trial is legal for 30 days.

This is for those who want to check that the after the installing of Reader Extension Server. Really it will work or not. So, before going to purchase, we should check that any service provided by any company can do the required task or not. that's why maximum number of companies providing this trial software kind of things. If i/we will get the satisfaction then easily anyone can upgrade these things and from the developer side we have to findout the solutions quick and tell to the our client's that it can be done or not. So, in less time it is best to use the trial version and use it and later you can upgrade and buy the software. This is my point of view.
