Upgrading from Oracle to a newer version can present several challenges. Here are some common hurdles along with potential solutions:

1. Compatibility issues:
   - Old applications or modules may not be compatible with the new version.
   - Solution: Conduct thorough compatibility testing using the latest Oracle tools, or engage an experienced consultant.

2. Data migration:
   - Upgrading may require transferring data from older formats to the new format.
   - Solution: Use Oracle's built-in tools like Data Pump or expdp/expdp for bulk data transfers. For complex data structures, consider scripting or automating the process.

3. Customizations and extensions:
   - Your organization might have customized or extended parts of yourOracle environment.
   - Solution: Prior to upgrade, create a backup of your customizations, extensions, and any related configuration files. After migration, carefully restore the customizations following best practices.

4. User acceptance testing (UAT):
   - It's important to have end-users involved in the UAT process to ensure that the upgraded system meets their needs.
   - Solution: Plan for UAT as part of the upgrade project timeline. Ensure that a test environment is set up, and user representatives are trained to conduct tests effectively.

In conclusion, upgrading from Oracle requires careful planning, execution, and testing. By addressing challenges with appropriate solutions, you can ensure a smoother upgrade process.
