I am unable to understand why (GSI) INFO: hostname = "UNKNOWN "
as per sap note 1519000 - ERROR: invalid migration key
" In the installation directory, a MIGKEY.log or test_MIGKEY.log is written at the same time. If the entry
....
(VK) ERROR: invalid migration key
...
is to be found here at the end of the log file, the migration key is incorrect. In this case, you must ensure that you have generated the migration key under the alias service.sap.com/migrationkey for the installation number of the source system. The information relating to OS, DB and so on is required for statistical purposes, but is not used for generating the migration key. "
can I create installation number of the source system in my portal then generate migration key from that installation number ?
