Unable to continue NSX upgrade after upload of MUB file

Products

• VMware NSX

Issue/Introduction

• After uploading of the NSX upgrade MUB file the next button is greyed out and unavailable.
• A warning is presented on screen as per the screenshot below stating "New NSX Upgrade version is not compatible with current NSX version, you cannot upgrade to this version".

Environment

VMware NSX T 3.X
VMware NSX 4.X

Cause

This is an automated version check to ensure the intended upgrade path is supported. It will not allow you to continue an upgrade that is not supported.

Resolution

Review the supported upgrade paths on the Interoperability Matrix - NSX supported upgrade paths page and ensure the version uploaded is valid to upgrade to from your currently installed version. To retry the upgrade simply re-upload the correct MUB for a supported version and continue as normal.
