Absolutely. The only case, when you can do the better things, is if you have
an instance in ASM already. Else you wil need to migrate it into the
clustered file system, ASM or raw device anyway, so proposed method works
better and is easy to implement.
Another (possible) choice is to set up RAC as a standby database and then
switchover so it became primary, then reinstall old primary as a second
node.

Hi,
You don't need to do so. Let say you have two nodes A (the current
database host) and B (a new node).
If you plan to go RAC, you can keep your database in the current node A.
You make the installations and configuration on the remaining node B. You
can have a RAC database running with just one instance on one node.
When Cluster ware, Oracle RAC is installed and ready to use, you move your
database to B as a RAC database. Your system is then available to your users
and you can now add the node A to your cluster, install Oracle RAC, and
start an instance of your database on it.

I know it is probably not recommended -
But is it possible to install Oracle clusterware ( + patch 10.2.0.2 )
while an instance is running on 1 node ?
Everything will be setup in advance :
Interconnect + Shared storage + host/accounts equivalencies ... + Full
backup ..
The goal is to try to decrease a system downtime when going to RAC ..
( And not having to rebuild a live instance/OS too .. )
Thanks in advance for sharing your ideas,
