I'm trying to migrate a web2py application to a new box.
Source:
 WS2k8 
 http://gutsup.com
 = http://95.211.128.165/openbrief
 web2py: _w2p_246
 using MySQL5.5 

Target:
 WS2k8 R2
 http://37.48.64.183   => welcome
 http://37.48.64.183/openbrief => crash
 _web2py281
 mySQL 5.6

What did i do?
 I transferred the database (w2pyopenbrief) from source to target using 
workbench (export/import)
 Defined the same user /password in target mySQL (web2py / / DBA)
 Downloaded new Web2Py (281)
 Packed openbrief app in source, read it in target

QUESTION: What did i do wrong?????
============================

## Define your tables below (or better in another model file) for example

## >>> db.define_table('mytable',Field('myfield','string'))
##
## Fields can be 'string','text','password','integer','double','boolean'
##       'date','time','datetime','blob','upload', 'reference TABLENAME'
## There is an implicit 'id integer autoincrement' field
## Consult manual for more options, validators, etc.

## More API examples for controllers:
##
## >>> db.mytable.insert(myfield='value')
