Warn users doing Office 365 migrations that content size will inflate in the process
When migrating content to Office 365, the amount of data will inflate due to use of temp database or something like that in the background. Sometimes it goes to double the size of the data from the source. This is reflected in Storage Matrix and it will get reduced over time (after a few weeks in some cases). It would be a good idea to have a warning so there's not issues with running out of space in Office 365.
