Given what was discovered in the migration for Exchange servers, I wanted to make the same attempt for Kerio Connect: I tried to launch a migration using SETTINGS -> CONNECTIVITY -> MAILBOX MIGRATION --> "SmarterMail" option.
I tried to migrate a mailbox containing very little data, 89 elements in all between mail, calendar, contacts, notes and activities (few elements for each type of object).
With this option SmarterMail is able to log in to the Kerio Connect server (while using the Exchange Server option it cannot even log in and immediately got an error) and the count of the emails to be transferred begins to rise.
But at this point the count of the email continues to rise indefinitely and never goes to transfer other types of objects such as contacts or calendar.
This is clearly wrong because I have only 35 mail in this TEST account.
See the images:
I canceled the migration after 2 hours and the email count had exceeded 20,000 and continued to rise ....
Looking at the log of the Kerio Connect we can see that Smarter Mail continues to LogIn and LogOut from Kerio several times per second. Below an extract of the logs:
Clearly, in this case too, the migration does not work correctly (even if at least it is able to login)
