Public Folders (calendars) Migration from Exchnage 2013 to Exchange Online Office 365 Groups

Hi All,

I am doing PF migration from Exchnage 2013 (supported CU) to office 365 groups. I have an article 

https://docs.microsoft.com/en-us/exchange/use-batch-migration-to-migrate-exchange-2013-public-folders-to-microsoft-365-groups-exchange-2013-help

Anyone has more step by step instructions with screenshots?

Is this good option to create groups online and , simply import pst there after migration or we should stick to the article?
