standby instance, log recovery

hello, *!

i am using this nice database since 7.3 and now with 7.5 i want to do 
some more advanced stuff :)

i want to run a standby instance that is constantly fed by log backups 
of a main instance, which seems to be a more or less standard task.

my main instance works nice. i disabled autolog since i want to control 
the log backups. i ran a full backup and used that to create the standby 
instance (recreated it from the parameters, then recovered the data).

now i am at the point where i want to load the first log backup (which 
was created manually by backup_start mylogbackupmedium) and it gives me:

recover_start importlog LOG 001
ERR
-24988,ERR_SQL: sql error
-8003,Log and data must be compatible

and knldiag.err shows the db-identifiers, which indeed differ. now, the 
documentation points out that the standby instance must not have been 
brought online, which of course happened.

the questions are: is this the only reason why this recover does not 
work? will it work when i create another instance the same way and do 
not bring it online? is there some way to change the standby instance 
somehow so that i accepts the log backup anyway? i had the impression 
that 'util_execute clear log' somehow might help, but it doesnt.

thank you very much for any advice,
        Raimund Jacob

ps: it probably does not matter, but the main instance was created from 
an older 7.4 instance.

pps: for the 7.4->7.5 and 7.5->7.5 copy operations i wanted to use the 
documentation from the chapter "Homogeneous System Copy with the 
Database Manager CLI". this documentation is wrong. it uses "INIT 
CONFIG" which does not exist anymore and it has the point wrong where 
you have to create the medium to import the data from.
