Answer: Make sure you upgrade the #SQL Server Management Studio to the Current Version. This happens because you have upgraded the Databases to the current version and the SQL Server Management is lagging behind.

More details:

The error message you've provided seems to be related to Microsoft SQL Server Management Objects (SMO). SMO is a collection of managed libraries that allows you to manage SQL Server instances and perform various database-related tasks programmatically.

The error message suggests that there's an issue with version compatibility in the context of converting or scripting SQL Server objects. Specifically, it appears that the SMO library is encountering an "Invalid version: 16" error.

Here's a breakdown of the information in the error message:

1. Invalid version: 16: This indicates that the code is trying to work with a version number that is considered invalid in the context of SQL Server scripting or conversion. The version number "16" seems to be the source of the issue.

2. Microsoft.SqlServer.Smo: This is the namespace where the `ScriptingOptions` class and related functionality are defined.

3. at Microsoft.SqlServer.Management.Smo.ScriptingOptions.ConvertToSqlServerVersion(Int32 majorVersion, Int32 minorVersion): This is the point in the code where the conversion of version numbers to SQL Server version is taking place.

4. The subsequent lines show the call stack, indicating the sequence of method calls leading up to the error.

Given this error message, here are some steps you can consider:

1. **Check SQL Server Version Compatibility:** Make sure that the version of SQL Server you are using is compatible with the version of Microsoft SQL Server Management Objects (SMO) you are using. Different versions of SMO may support different versions of SQL Server. It seems that the error stems from version "16," so ensure that your SMO library is compatible with SQL Server version 16.

2. **Update SMO Libraries:** If you are using a version of the SMO libraries that is older than the SQL Server version you're working with, consider updating the SMO libraries to a version that supports your SQL Server version.

3. **Check Code for Version Handling:** If you are writing code that uses SMO, review the code to see if you're specifying or handling version numbers in a way that might be causing the error. Ensure that the version numbers you're working with are valid within the context of SMO.

4. **Debugging:** If you have access to the code, you might need to debug the specific piece of code where this error is occurring. Examine how version numbers are being used and passed around.

5. **Microsoft Support:** If you're unable to resolve the issue on your own, consider seeking help from Microsoft support resources or relevant developer communities. They might be able to provide more specific guidance based on the context of your code and environment.

The provided error message doesn't give the full context of where and how this code is being used, so further investigation into the code and environment might be necessary to pinpoint the exact cause of the error.
