you can create new tablespaces in your filesystems and then move objects from tablespaces with datafiles in asm to the new ones.
that will work for your user schemas, and in many cases can be done online.

you can't do that for the SYSTEM tablespace though.

or, shutdown your database, and you can simply use asmcmd  cp command to copy files while they are offline. then alter database rename to tell the database where to find them.

then restart the db.

you could use both methods.  Use the first for user schemas, use the latter for system


you can also use RMAN to copy your files instead of asmcmd
