SharePoint 2019: feature 'MySiteMicroBlog' needs upgrade ; Database is up to date, but some sites are not completely upgraded

Question

• Test SharePoint 2019 MinRole farm patched to KB4464556 May/2019
• Tested Mysites database migration by restoring a full backup from a production 2016 farm but for several MySites this feature needs an upgrade:

Feature 'MySiteMicroBlog' Current Version: 15.0.5.0 < Latest Version: 15.0.6.0. Feature needs and upgrade.

• In Central Administration > Manage Databases Upgrade Status
  MySites Status:

Database is up to date, but some sites are not completely upgraded.

Feature upgrade incomplete for Feature 'MySiteMicroBlog' (Id: 15/GUID') in Web 'http://mysites/personal/username'. Exception: 0x80070002

How can I upgrade this feature?

Answer 1

As I used Mount-SPContentDatabase after restoring backup in SQL and it runs an upgrade on the database, results gets logged in the ULS LOGS folder file name starting like: Upgrade-YYYMMDD-HHMMSS-###-xxxx.log.

• Using ULSViewer, I filtered by Level: ERROR and Message: Feature upgrade incomplete for Feature 'MySiteMicroBlog'
• Got all Mysites URLs failing to upgrade MySiteMicroBlog" feature from that log
• Using cmdlets shown here on steps 8-10 I upgraded "MySiteMicroBlog" feature on each MySites (Note: Upgrade returns exception 0x80070002 but it works anyway).
• Logged as the farm account in Central Administration, delete MySites content database, wait 2 min aprox and added it back.

Following these steps changed database status to "No Action Required" and I finally resolved this issue
