Migrating from sugarcrm 4.5.1j (Build 1205) to 5.0

[nbentzinger]

System:
VM CentOS5.2
php 5.2.8
mysql-server-5.1.30-1
apache 2.2.3-11

php.ini:
max_execution_time = 3000000
max_input_time = 6000000
memory_limit = 128M
upload_max_filesize = 128M

config.php
fileupload= 22000000

I'm trying to update 4.5.1j up to 5.x. I have downloaded SugarCE-Upgrade-4.5.1-to-5.1.0c.zip and ran through the admin wizard but it hung at the fourth step with nothing but lines like:
Adding for Leads
Adding for Contacts
Adding for Accounts
Adding for Opportunities
Adding for Cases
Adding for Notes
Adding for EmailTemplates
Adding for Calls
Adding for Emails
Adding for Meetings
Adding for Tasks
Adding for Trackers

Searching brings up lots of grief about 5.1.0b and suggestions for commenting out three lines in a end.php (which don't exist for my end.php file). Restoring from backup and running the silentUpgrade.php with the switches gives the same minimal error output:

/usr/bin/php -f silentUpgrade.php SugarCE-Upgrade-4.5.1-to-5.1.0c.zip  /var/www/vhosts/sugarcrm/upgrade-silent.log /var/www/vhosts/sugarcrm/ nbentzinger

I'm at my wits end here. This 4.5.1 was moved to a clean CentOS5.2 install due to the php5 requirement. We use no additional plugins. How can I migrate/update this data and am I going to have this much trouble moving to 5.2?

Hi,

I believe you can't upgrade a 4.5.1j system to a 5.1 directly using PHP 5.2.8 as 4.5.1j doesn't support 5.2.8.

I would suggest following:

- Update from 4.5.1x to 5.0 on your currrent server, then copy this version to your new server and finally do the upgrade to 5.1x.

Also I would raise the memory_limit value to over 500M, can't have enough memory
