Hi Garot,
How is the visual diagram coming along ?
I'd be good to have a good idea of core system specifics so that DB design can

Thanks,

we'll need a user-friendly architecture diagram with a hopefully one to one
mapping to DBSchema Table Elements..(run the napkin thru a scanner and publish
it)
once the Table Elements are defined then we'll need to populate Tables with
columns..determine Primary Keys with Foreign keys..get the
I have not as yet created the visual or really mapped anything out yet, it has
been a somewhat oddly long working strectch for me this last week, so I will

done this many times in the last years and it takes 30 seconds
if you are fast enough to type the slave-commands

It's the sequence that is tricky.
1. STOP SLAVE
2. CHANGE MASTER

Do it wrong, and you miss or duplicate replication stuff that happens between
#1 and #2.
Could you please lay out the precise steps, so that I can understand how
un-tricky it can be.

Are you trying to promote a slave as a new master and replace current master or
create intermediate slave? If it is the latter all you need to do is to:
1. Stop the slave

4. Start your
