We are using 7.0 crsytal report. Now we decide to shift from 7.0 to 8.5
We install 8.5 on 1 pc and convert one report manually. But when exe runs, it failes and give error
20535 - incorrect session parameters

Is there any way to convert all reports into 8.5 automatically ? what is the way to convert report into 8.5 ?
We are a company in development. So there are many projects where we want to change/convert this procedure.

Help Me !!!!!!
