Dear Community,
Would you please explain the difference regarding the information provided by online upgrade simulation service and pre_upgrade_verifier script from migration tools.
Do they provide the same information regarding the readiness of management database for the upgrade? For me it looks that online service is worth using a long before the upgrade when you only start preparation and have enough time to fix all the issues. While pre_upgrade_verifier seems to be the tool for use during the upgrade process to ensure you`re safe to proceed.
Are there any benefits of online simulation service, for example, more detailed suggestions how to fix particular error/warning, etc?
Thanks in advance for help.
Regards,
Kirill
