= How To Migrate from Phabricator To Phorge
The process of migrating from Phabricator to Phorge is very similar the [[ https://we.phorge.it/book/phorge/article/upgrading/ | Upgrading Process ]], except that you'll be switching to a different remote.
== Assumptions and Requirements
This document makes several assumptions about your install:
1. We assume you've you've installed Phabricator using the official, supported instructions in https://secure.phabricator.com/book/phabricator/article/installation_guide/. That is, we assume you've used `git clone` to get the code from Phacility's GitHub mirrors.
2. We assume you've made no local changes ("fork") to the code. If you've added a library that's fine, but we assume no changes to the `phabricator` and `arcanist` code bases.
If you have made local changes to your install, then we assume you're comfortable enough with `git` to adapt.
== Process
=== Get Current Version
First, you'll want to check the current version of your Phabricator install. Phabricator and Phorge use Git commit hashes as "version". You can see your current versions of `phabricator` and `arcanist` packages by visiting your install `/config` page.
You'll want to be reasonably up-to-date before migrating - see [[ https://secure.phabricator.com/w/changelog/ | Phabricator's Changelogs ]] for details. We highly recommend updating at least to an early 2022 version.
Currently, Phorge is up to date with these Phabricator commits:
| Repository | Commit hash | Date | Comment |
|---------|---|---|---|
| Phabricator | `9426765a2c6a` | Jun 14 2022 |Flatten "RemarkupValue" objects when setting field defaults for custom forms |
| Arcanist | `85c953ebe4a6` | May 18 2022 | Fix a PHP 8.1 repository marker issue in Mercurial |
If your install is more advanced then these commits, the best approach is probably to wait for Phorge to catch up (or ask a Core team member to update).
=== Updating
1. Stop the webserver and daemons.
1. Backup your install - Database and files storage.
3. Update the `origin` address in each repository:
```lang=shell
$ cd ./phabricator/
# This will print out `master` or `stable` - it's the branch you're using:
$ git rev-parse --abbrev-ref '@{u}'
$ git remote rename origin old-origin
$ git remote add origin https://we.phorge.it/source/phorge.git
$ git fetch origin
# This creates a backup of your current state:
$ git branch last_known_good HEAD
# Configure your new remote: You can use `origin/stable` instead that's the branch you've been using.
$ git branch --set-upstream-to=origin/master
$ git pull
# Repeat for Arcanist directory:
$ cd ../arcanist/
$ git remote rename origin old-origin
$ git remote add origin https://we.phorge.it/source/arcanist.git
$ git fetch origin
$ git branch last_known_good HEAD
# Configure your new remote: You can use `origin/stable` instead that's the branch you've been using.
$ git branch --set-upstream-to=origin/master
$ git pull
```
