When I start this migration - Exchange ask for the endpoint - what of endpoint is necessary  fill  ?
I fill our FQDN   , but after this I receive information, that connection to  this FQDN cannot  to complete

Here are a couple of things you can try...

  1. Run IISRESET on each Exchange server
  2. Restart each Exchange server
  3. Ensure port 80 and 443 are open to the Exchange server you configured for hybrid from outside of your environment

These Endpoint s are important because you will be using them for migrating the mailbox with MRSproxy so you need to make sure you have MRSproxy enabled on hybrid server so make sure this FQDN points to your CAS servers where you have MRSproxy enabled

But please explain me more, how can I check third  - Ensure port 80 and 443 are open to the Exchange server you configured for hybrid from outside of your environment ?

Moreover, in case if you wish to automate users mailbox migration, you may try using Shoviv exchange manager which should be an ideal solution to accomplish this task in hassle-free manner.

You can use telnet from an external machine or a port scan tool.
