Postbox 7 Migration Guide

Follow

 

This guide contains important information for people who are upgrading from Postbox 5 or earlier to Postbox 7. If you are migrating from Postbox 6, simply run the installers.

 

Installation Overview

Existing Settings are Copied, Not Modified

When Postbox 7 is run, it will copy settings and files from your previous Postbox 5 or earlier install into the new Postbox 7 data directories, leaving your previous data directories unmodified. This preserves full backward compatibility with your previous version of Postbox.

Concurrent Operation

Separate data directories mean that it is possible to run Postbox 7 concurrently with older versions of Postbox. If you wish to run concurrently, there are a few extra steps to follow:

On macOS, copy the Postbox.app file to the Desktop, rename it "Postbox 7," then copy it to your Applications folder.

On Windows, specify a different installation directory for Postbox 7.

Disk Space

Since Postbox will be copying data from one install to the next, you may wish to free up some disk space from your previous version of Postbox prior to installing Postbox 7. An easy way to do that is to delete your ImapMail cache.

Start Postbox 5 (or earlier), then go to the "Help" menu and select "Trouble Shooting..." and then select the following:

_X_ Reset IMAP mail databases and Search Indexes

Then restart Postbox 5, then Quit Postbox 5.

 

Installation Options

Postbox may present to you migration options during your install.

Migrate from Postbox 3, 4, or 5 Option

If you have used version 3, 4 or 5 (within the last six months), Postbox will offer to migrate some (but not all) settings and data from your previous install to version 6.

During migration, Postbox 7 will:

  • migrate your account settings and passwords
  • migrate your POP and local mail
  • migrate Filters, Signatures, Responses, Quick Posts, and Address Book data
  • migrate some (but not all) user preferences

Postbox 7 will not migrate:

  • IMAP mail, as this will be downloaded from the server
  • many hidden preferences set using the Config Editor
  • indexing data (a re-index will be required)
  • UI customizations such as Account Groups or Toolbar settings

Clean Install Option

If you select "Clean Install" nothing will copy over from a previous Postbox install! You will be starting from scratch.

If you select Clean Install by mistake, and now see none of your data when you start Postbox 7, don't worry! All of your data from your previous version is still intact! You simply need to restart the migration process:

  1. In Postbox 7, go to Preferences (macOS) or Options (Windows) > General, and select the checkbox for Show Profile Manager at startup.
  2. Restart Postbox, and it will enter into the Profile Manager. Create a new profile, give it a name, then start Postbox with that profile.
  3. When you reach the Migration Assistant, select the option to Migrate from Postbox 3, 4 or 5. 

 

Installing Additional Profiles 

The Postbox 7 migrator only imports one profile at a time, so if you would like to import additional profiles, here's what to do:

1) In the running profile, go to Preferences (macOS) or Options (Windows) > General and select the checkbox for Show Profile Manager on startup.

2) Restart Postbox, and it will enter into the Profile Manager. Create a new profile, give it a name, then start Postbox with that profile.

3) The Migration Assistant will reappear, allowing you to select a second Postbox 3, 4, or 5 profile.

Repeat these steps for each profile you wish to import.

 

Is it safe to remove the older Postbox directory after installing Postbox 7?

We do not recommend removing anything from your hard drive unless absolutely necessary. But if you need to remove the older Postbox folders, you can find them here:

macOS:

~ [your home directory] / Library/ Caches / Postbox
~ [your home directory] / Library / Application Support / Postbox

Windows:

Users\username\AppData\Roaming\Postbox
Users\username\AppData\Local\Postbox
