Is there something similar to PerformUpgrade, but then for Tasks?
I have package xyz.dtsx with version 1.0 of a custom task. Now I install version 1.1 (with one extra property) and open package xyz.dtsx again. It will generate an error saying the new property is missing in the XML.
The "xxxxxx" node cannot be found in custom default persistence. This error occurs if the default saved XML of an extensible object was changed in a way that a saved object is no longer found, or if the extensible object itself changed.
For custom transformations there is the
PerformUpgrade method, but is there something similar for tasks?
MSDN is mentioning
Update and
CanUpdate, but there is very little info and they are marked as deprecated:This member will be removed in a future version of Microsoft SQL Server. Avoid using this member in new development work, and plan to modify applications that currently use this member
