I have not upgraded from Intralink 3.x to 8.0 & most the nation has not either.
Its probably not been out long enough to be bug proof, so patches &/or service
packs are probably part of the full upgrade.

Jeff's military time requirements have caused him to do it earlier than most.

I cant say it will be easy or hard, I dont know his your network, back-up
system or release level configuration, etc.

I also cant tell you now how long it will take because I dont know how much
early preparation you have done & how PTC properly configured of an enviroment
you have. If I have to do the account downloads & upgrades, it will take longer.

If he has the same demanding time restraints as he specified before, its a
no win situation.

I had planned on following PTC's detailed steps to upgrade & migrate. I dont
see how anyone would have any other logical method.

Intralink 8.0 is very similar to PDMLink, where you install an Apache web
server, a tomcat servlet engine, an Aphelion/Ldap service/server app & Oracle.

The difference is windchill/pdmlink software verses intralink 8.0. I was part
of a team to install windchill 6.x & have been traioning on PTC University's
Windchill training. Which practically walks you through a windchill install.

If migration is not complete, because of extensive family table issues, PTC
provides sql scripting to complete migration. I have used sql scripting for
intralink before.
