======v3/4 - Move the message store to a new folder/drive======

This guide assumes you want to just move the VPOP3 message store/database to a new folder on the same PC, and leave the VPOP3 installation directory where it is.

  - Stop VPOP3
  - Stop PostgreSQL
  - Remove the PostgreSQL service
  - Move database to the new folder
  - Reassign permissions for PostgreSQL
  - Reinstall the PostgreSQL service
  - Restart PostgreSQL
  - Restart VPOP3

Note that we can do this for you remotely if you wish, there is a small charge for this (currently £50 + VAT). Contact us on 01484 855800 if you wish us to do it for you.

Please note that we do not recommend or support moving the message store to a networked or external (eg USB/Firewire) drive.

=====Stop VPOP3=====
Go to Control Panel -> Administrative Tools -> Services, and stop the 'VPOP3 Email Server' service

=====Stop PostgreSQL=====
Go to Control Panel -> Administrative Tools -> Services, and stop the 'PostgreSQL-VPOP3' service

=====Remove the PostgreSQL service=====
At a command prompt, navigate to your VPOP3 directory, then the **pgsql\bin** directory under that

Run
  pg_ctl unregister -N "PostgreSQL-VPOP3"

If that comes back with ''pg_ctl: service "PostgreSQL-VPOP3" not registered'' then try running this instead:
  pg_ctl unregister -N "pgsql-8.3"
=====Move database to the new folder=====
Move the VPOP3 'pgsql\data' folder and ALL sub-folders to the new location (eg 'd:\vpop3data')


=====Reassign permissions for PostgreSQL=====
You need to assign permission for the **postgres** user to the new folder (eg 'd:\vpop3data')

To do this, go to the parent folder in Windows Explorer (eg if the database has been moved to 'd:\vpop3data', go to the 'd:\' folder) . Right-click the new data folder and choose Properties, then Security. Add permission for the **postgres** user to have full permission to access this folder. (On an Active Directory Controller, the **postgres** user is a domain user, on all other types of PC, the **postgres** user is a local user).

=====Install the PostgreSQL service=====
At a command prompt, navigate to the VPOP3 directory, then the **pgsql\bin** directory under that

Run
  pg_ctl register -N "PostgreSQL-VPOP3" -D "<new data folder>" -U postgres -P vla8Pi4cluwrouDiERiU

e.g. Run
  pg_ctl register -N "PostgreSQL-VPOP3" -D "D:\vpop3data" -U postgres -P vla8Pi4cluwrouDiERiU

The 'new data folder' is whatever the new name of the 'pgsql\data' folder is. It is //not// the name of the folder //containing// the new data folder, but the name of the new data folder itself. A simple way to tell this is that the "new data folder" is the path of the folder where the **postgresql.conf** file now resides. So, if your 'postgresql.conf' file is in the 'd:\vpop3data\data' folder, you should specify '' -D "d:\vpop3data\data" '' in the above command.

For more information on the pg_ctl command, see the [[http://www.postgresql.org/docs/8.3/static/app-pg-ctl.html|PostgreSQL documentation]]
=====Restart PostgreSQL=====
Go to Control Panel -> Administrative Tools -> Services, and start the 'PostgreSQL-VPOP3' service

=====Large Message Store=====
In VPOP3 versions 3 and 4, large messages are not stored in the database, so, if you wish to move those as well, there is a further couple of steps before you restart VPOP3:
  - move the VPOP3\_messages folder tree to the new location
  - In the Windows registry, find **HKEY_LOCAL_MACHINE\Software\PaulSmith\VPOP3** and set the **MessageStore** value to point to the new location

=====Restart VPOP3=====
Go to Control Panel -> Administrative Tools -> Services, and start the 'VPOP3 Email Server' service
