Data migration from MS Dynamics

[Kertscher]

We want to be migcate data from MS Dynamics to EspoCRM.
We want to be expot the data from MS Dynamics to CSV format.
My problem is the primary key value from the tables account and contact.
How I can generate the primary key value?

[Kertscher]

For example the Id from an account: 5d2de5882bec0c928.
My question is, can I create this random or does it have a certain logic.

You can generate a random string.
