Greetings everyone,
We have a bunch of C9200 that we have to update to 17.9.5 from 16.12.4. And I am worried about the text from the release note below :
Upgrading the software image from Cisco IOS XE Gibraltar 16.12.x to any of the later releases can result in a persistent database operation failure and after which the persistent database cannot be restored.
To avoid the persistent database operation failure, use the dir bootflash:.dbpersist command to list all DB persist files and then use delete bootflash:/.dbpersist/folder_name/file_name and bootflash:/.dbpersist/folder_name/file_name.meta commands to delete individual database and meta files from each persistent database folder.
from https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9200/software/release/17-9/release_notes/ol-17-9-9200/limitations_and_restrictions.html
I am not an expert in switches and I wanted to know what is dbpersist files, what are the risks and what I need to do, to avoid loosing any config nor data.
Thank you for your answers.
Best regards.
