Hi Inosh,

Please find my questions regarding this process as follows.

[1] How are we planning to get an OOT for each serial and in-case of an
unenrollment, what is the process of getting a new OOT?
[2] Here, are plainning to do an enrollment without associating a user? if
not, how will be other management functionalities carried out upon
post-enrollment?

Thanks.
