Looking to compare latest NPM features with previous versions of NPM?
The NPM new feature summary offers a comparison of new features and improvements offered with this release.
This article provides a workaround to import nodes from an old NPM database (10.2) to a new implementation of NPM (11.5.3 and later). Nodes cannot directly be imported between these two versions because the database structures are different.
The process includes a migration to a new version of SQL and upgrading NPM.
If you are upgrading from NPM 10.3 or earlier, we recommend starting with a fresh install. Read this article for details.
