The COVID pandemic drove many institutions and courses to move online, quickly and without the time and effort normally provided for online MOOC courses.
In some cases, universities and colleges still oscillate between online and on-campus as outbreaks occur and then fade away. It is best to have some plans and material at hand for the shifts.
Do not attempt best practice or even consider it the first time you are going online in a rush. Do not think about doing it. There is not enough time and resources to do a full, appropriate re-development. However, do not just take your classroom course, record yourself talking to them as if you were in a classroom. Do not just post your old notes. Invest some time to do the minimum redesign and redeployment. Please!
That being said, it is probably wise to invest some time during the term and after to 'fix' things up a bit; it is likely that portions of the rushed material will be used again in hybrid situations.
