Changed data type varchar(140) to blob

Just wanted to have one clarification on this error:

OperationalError: (1118, ‘Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs’)

And due to this, I change so many custom fields from varchar(140) to blob, so just wanted to clarify will it make any issue in future updates, and will it remain as it is or after update I have to change them back to blob again?

If it is a custom field, it should not be a problem.
