GTID vs mysqldump

[fdsds fdsfsd]

hello,

reading the doc ch 18.1.3.4 Restrictions on Rep with GTID's

"GTID mode and mysqldump. It is possible to import a dump made using mysqldump into a MySQL Server running with GTID mode enabled, provided that there are no GTIDs in the target server's binary log."

Does this mean mysqldump can still be used for backups, but no restore ?

how do I restore to a master that will obviously already have GTID's

I dont get this

thanks
