Upgrade from 7 to 10. How much effort?

[shine67]

Hi,

we are trying to upgrade due to the Sybase upgrade to 12.5. I know that PB 7 is no longer supported under this Sybase version and don't want to take a risk of suddenly running into troubles. But at the same time, I don't want to spend too much time on this application we built long time ago. I know it's kind of a very vague question but how much effort should I make for the upgrade? It's not a big application with about 70 windows/data windows involved. What in particular do I have to do to upgrade?

Thanks for any input.

Migrate the application and address whatever comes up. Since I don't use Sybase databases I don't know if you will have to switch drivers.

If you can get a clean build make sure you test every database call the application makes to verify there is no problem.

Shine,

The diff is huge. PB10's default characterset is UNICODE where as PB7's characterset is ASCI.

I just now migrated application from PB8 to PB10.

You need to fix following problems

1) If you have declared external functions and it uses string as argument or return value, sufix it with Ansi;

2) Remove duplicate varibles. PB8 allows you to declare duplicate variable declaration of type array.

3) Script overflow may occur. If any event contains lines more than 1500 lines, optimize them. Move them to some other function.

Refer to

before proceeding.

Hope it will help you.

Regards,
Abhijit.

When I migrated all my external function calls were updated automatically by the process.

mbalent,

I encountered problem while migrating one object which was having external function. Rest all objects successfully migrated and were automatically updated.
