Upgrade 3.3.4 to 4.2.b

[mathieu_i1]

Hi,

I'm trying to upgrade an alfresco enterprise 3.3.4 to alfresco community 4.2b.
To do that, i'm upgrading 3.3.4 to 3.4d (last community in v.3) first.

When I do this upgrade, logs return me lots of lines which say "false false null" and an error about PDFox.

Where those errors could come from and hos to fix that please ?

Hi Mathieu,

Were you able to resolve this issue ? I am having the exact same errors after upgrading from 3.2r2 to 3.4.

Anyone can help ?

Hi
Like to know ur up-gradation steps, I have done a couple of upgradation, my steps are
Copy the alf_adir
Take the Database backup
mv the present install folder to another name 
Install the next release, do not start the service
copy the contents of previously copied 'alf_dir' to the newly installed instance 'alf_dir"
start the service
up gradation over
