Move to Another Server? - Joomla! Forum - community, help and support

a client called me week complaining host company , requested take control of domain , website.
i transferred domain control , prepared server website.

i went old server, downloaded client's files , retrieved mysql dump of database. uploaded files server , inserted sql statements.
the next step updated configuration.php contain new details of database. tested site using sub-domain of pre-hosted website.

i have yet change dns of domain old server new server. have never dealt joomla site before , nervous might break , have change dns. can tell me if on right path?
is there steps missing?

also, related not important (i think), within configuration.php there 2 paths tmps , logs folders. know location of log folder on server. need tmp path too?

definitely need temp path, same path logs, make folder called /tmp.

did test work in subdomain? if so, did right.
