I will be upgradeing to BL 7.6 . Would it be easier to do the 7.6 upgrade before or after the move
of 7.4.3 from /usr/nsh to /opt/nsh ?
when you upgrade you can't specify a new directory. you will need to uninstall and re-install.
you should only need to keep the bladelogic.keystore file (/usr/nsh/br/deployments/_template) and know the keystore password. though I would keep a backup of the original install just in case. you'll have to know the db password and such to reconfig everything w/ blappconf or blasadmin.
