Can 6.1 and 7.0 run on same machine?

Question

I have WL6.1 with 5 services/domains running on the same machine. I want to install
WL7.0 on the same machine and migrate one domain at a time without interrupting
the others. Is
this possible? If so, should I install to the same BEA Home directory or use a
new one? What
about the licences? I need to make sure 6.1 keeps running while I'm installing
7.0.

Answer 1

Nope the only thing you need to worry about is not having them run on the
same port. Right now on my little old laptop I have running 5.1, 6.0, 6.1
sp5, 7.0 sp2 and 8.1, plus our latest code line. :D

From your posting below, I think we can have multiple versions of the WLSon the
same machine as long as:
1. Each WLS version has a different HOME directory and
2. All Classpath specifications are specified in the Classpath variable inthe
Startwls.cmd.
Apart from the above, is there anything more that needs to be done. I aminterested
in running WLS 7.0 SP2 and WLS 8.1 on the same machine for developmentpurposes.
The applications deployed on each Server are not expected to interact anyway
with one another.
Thanks,

License files are stored in your BEA home, you can intsall to the same
BEA
home. You need to follow the instructions:
http://edocs.bea.com/wls/docs70/install/instlic.html#1036174
Prior to installing 70 you will need to make a backup copy of the 6.1
license file, then install, then remerge/update. Servers only check
the
license file when starting up or when a new deployment/service is made,
currently running servers and services/apps will still work fine.
I am not sure about being able start more than one service at a time
with
different versions. I would just start the new domains via the command
line
until you have migrated them and then install as a service.
As for 7.0, if your moving upwards I would go to 8.1, which was a
hardening
release on top of 7.0 and despite the numbering that marketing came up
with,
from WLS perspective this is a "7.1" release.
Additionally you should be able to just copy your domains from 6.1 to
a new
location, point 8.1 at them and just start. The only issue would be
application file paths. If they are archives the servers alwaysstage/unjar
a copy anyway, if they are exploded then you will possibly have issues
with
two servers trying to read/write from the same directory. Thus it might
be
prudent to also copy your 6.1 applications to a new path and change the
paths in the config.xml appropriately (unless they are relative).
