In my work environment, we use NPM 11.0 but after sometime, I observed that upon adding new nodes to it, I would have to restart Orion Services Manager before the new nodes get polled for real time information. Although, a ticket has been raised, and I have been advised to upgrade the NPM to 11.0.1 because a hot fix exists for my issue but it can only work on NPM 11.0.1.
So now, I want to ask if an upgrade in the NPM would affect my historical data in the database.
Take note, the Solarwinds modules are installed on a server, which is different from where the database is located.
I just want to clear my doubts.
The upgrade should not remove any historical data captured in the database. There are schema changes being done, but it won't affect the data stored. While there won't be data collected during the upgrade causing a small gap in data, all your historical data will still be intact at the end of the upgrade.
