sure there are manuals on support.emc.com for IMT - called called VNX data import CEPP is in the CLI manual like NDMP in the next release 4.4 a new manual for NDMP published  there are around 14+ PDF manuals for Unity - I would suggest to download them all then you can search across them all  you can also download the Unisphere help for offline use
Is there a manual I can look at rather than ask a lot of questions which will probably be answered with RTFM  Also unity and CEPP, is there a similar reference manual ?  Also unity and NDMP, is there a similar reference manual ?  ( there is a kind of theme developing here [IMAGE] )
question re Inband Migration Tool (IMT) as it relates to file migration
