WSOD on migration between platforms [#1480416]

Upgraded barracuda & octopus, trying to migrate a site form /002/drupal7.12 to /003/drupal7.12
old platform was with custom modules on platform level and themes on site level, modules & libraries folder is copied

getting WSOD on all pages exept /update.php

what I did:
cloned site on old paltform -> works well
cloned another site on old paltform -> also works well
cloned another site on new platform -> also works well
cloned (first) site on new platform -> WSOD

http://omega8.cc/how-to-disable-all-caching-and-aggregation-115 - site is with dev. alias - no change, WSOD on all pages
repeated the same with site in maintenance mode - WSOD on accesing front page
seems, like some module is breaking things

You should never clone any site to the new platform directly.

To debug WSOD use "dev." subdomain. Or check the logs in /var/log/php/*

Here is an example of supported workflow: http://drupal.org/node/1479106#comment-5722098

as I wrote in original post - did EXACTLY as you recomend:

Example of less-paranoid workflow:

1. Create a new platform with *new* contrib modules
2. Re-verify the old platform.
3. Clone the site in the old platform.
4. Re-verify the new site clone and the original site.
5. Migrate cloned site to the new platform and re-verify it.
6. Clear all caches and make sure that the cloned/migrated site works fine.
7. Now migrate also your live site and re-verify it after migration.

Even if some slight more paranoid modifications to the workflow - result is the same: one site is ok, another is not. Tried many times with various domains-subdomains,
/var/log/php/* is empty, all files 7 bytes long, getting the same WSOD when accesing cloned site with dev.clone.site.com
