What could be the possible problems if I change of technology or if I change version of .Net or Oracle?

.Net
If you migrate your applications from version x to version x+1 of .Net: Visual Guard supports .Net technologies.

If you migrate your application from .Net to an other development platform and language:

Starting version 3.1, Visual Guard is able to secure any type of application as long as they are able to call web services.
Note:If you secure a non .Net application with this version, dynamic technical action will not be available.

You would keep the whole structure of your security (end users, roles, permission sets, permissions) and would have to write the technical actions in the code of your new/migrated application.

Oracle:

If you migrate your applications from version x to version x+1 of Oracle: Visual Guard supports Oracle 9i and up.
If you want to migrate your database form Oracle to something else:
Visual Guard also supports ms sql server. A free version is available on Ms website.



Visual Guard - Version 3.1.911.5
