7.2.3-7.4.2 migration

Hello,

First let me introduce myself as i'm posting for the first time.

I'm a project manager working for a french e-crm company, that is dealing with packaged email managing solutions, both inbound and outbound.

Our technical solutions relies on perl, c++, corba, apache and Postgres 7.2.3.

We were waiting for 7.4.2 to upgrade.  As it is out now, i have some questions to ask.

The point is that we must upgrade our clients database, with loads of data in.

First, is it possible to upgrade directly from 7.2.3 --> 7.4.2 : ie dump the 7.2.3 datas, upgrade to 7.4.2, then restore the 7.2.3 datas?

or shall we do 7.3 upgrade, restore datas, dump, then 7.4 db upgrade, restore datas?

I would then appreciate if anyone can report a similar experience, problems faced and so on..

Thanks a lot by advance
