No, not necessarily. There are scripts provided to upgrade the catalog.
But you should consider switching from sqlite to either MySQL or
PostgreSQL.
You will probably want to keep your catalog, but I'm almost sure that
a sqlite dump is not compatible with the other databases. Without ever
having tried a database engine change, I suspect that changing the
dump is possible using tools like sed or awk, but you should be
prepared to invest a day or so...

That's a bug in the manual... bf should probably be \bf in the manual
source which would simply mean bold face. So, the command you use is
really only 'run'.

Actually, I'd do this different.
Kepp the old server around to be on the safe side.
Copy all the relevant files to the new one - mainly configuration,
bootstrap files, catalog dump.
Create the catalog on the new machine and load the dump.
Modify the configuration on the new machine as needed. I would suggest
to simply change the relevant addresses and keep all the names the
same. (I know this can be confusing because you can not easily
distinguish if jobs were stored to the old or new SD, but you won't
have to change the client configuration, for example.)
Start Bacula on the new machine and see if the catalog is ok. Try test
restores. Get the status of the defined clients. Fix any remaining
problems.
Run some jobs manually. Hopefully, there are no problems.
That should have been it, your new backup server is ready for use.
Keep the old one for some time, anyway, but make sure you don't run
both of them at the same time...
