New MacBook, need to install 1Password but have agilekeychain file format

@FiberNut - thanks for taking the time to write out such a detailed post. Since you clearly seem to be interested in the nitty gritty of this, let me reply with a similar in-depth post.

There is indeed a small percentage of users for whom the Agile Keychain conversion isn't working -- this is mostly due to malformed or corrupted data/references in the Agile Keychain, often with attachments. We're sorry for the trouble, and we're here to help those few users for whom this is an issue. That said, keychain conversion from Agile Keychain to OPVault should happen AFTER 1Password 7 for Mac imports the data directly from the user's previously-existing SQLite file. In other words, the two processes are independent, so even if keychain conversion fails, you should still get the data before that.

Even in a case where that somehow did NOT happen, I would avoid using the export-to-1pif option unless there were no other way. 1pif is a great export format if you need a readable copy of your data to take with you elsewhere, but it has some significant drawbacks, not least of which is that it's a fully decrypted, plaintext copy of your data. That's easy to forget and leave lying around on your hard drive - or if you have Time Machine or Backblaze turned on, it's easy to get a copy stored in a backup -- something you just don't want. .1pif also does not preserve Folder hierarchies if you have those. If not just keychain conversion but actual import of data from version 6 did not occur, I would do this instead for anyone else in your shoes (drawing where I can from your steps):

If you are staying with standalone setup in 1Password 7 for Mac:

1. Open prior version 1Password 6. [If you already removed it, thats ok reinstall it].
2. Follow these instructions to convert your data form Agile Keychain to OPVault
3. Quit 1Password 6 and the Mini by typing ^⌥⌘Q (or just holding down the Control and Option keys as you choose Quit from the 1Password menu)
4. Delete 1Password 6 for Mac. Don't use any app cleaners or uninstallers to do this, as these programs can remove more data than we want them to. Just drag the 1Password 6 app to your Mac's Trash, then empty the Trash.
5. Run 1Password 7 for Mac again. You will not get asked to convert because the conversion is already done.

If you are converting from a standalone setup to a 1password.com membership:

Run steps 1-4 from the above instructions, then:

1. Run 1Password 7 for Mac again. If you already have a 1password.com account, sign into that. If you want to create a new one, click the "Subscribe Now" button to do so.
2. Once you're signed into your 1password.com account in 1Password 7 for Mac, navigate to Preferences > Advanced and check the box marked "Allow creation of vaults outside of 1password.com." This will ask you for your Master Password, and then it will create a new, empty standalone, "Primary" vault.
3. Visit Preferences > Sync and set the Primary vault to sync with Dropbox. Navigate to the OPVault you created in step 2 above. Let everything sync.
4. Use these instructions to move your data from Primary to your 1password.com vault.
5. Make sure Primary is empty, then return to Preferences > Advanced and UN-check the box marked "Allow creation of vaults outside of 1Password accounts." This will remove the now-empty Primary vault, leaving you with only your 1password.com account, with all your previous data in it.

This will give that same result you want -- your older data, now in your new 1password.com account -- but without the messy and insecure step of exporting unencrypted data. :)

@aszajlai - no worries, and sorry for the delay in our reply. I would do this on your Mac. You won't need to do it anywhere else; one conversion is all you need, then on other devices, you simply need to turn OFF syncing with the existing Agile Keychain, then turn it back ON but point it to the OPVault this time. Here are the instructions. Let us know if you have any questions! :)
