# From 3.0 to 3.1
*Make sure you view this [upgrade guide from the `master` branch](../../../master/doc/update/3.0-to-3.1.md) for the most up to date instructions.*
**IMPORTANT!**
In this release **we moved Resque jobs under own gitlab namespace**
Despite a lot of advantages it requires from our users to **replace gitolite post-receive hook with new one**.
Most of projects has post-receive file as symlink to gitolite `/home/git/.gitolite/hooks/post-receive`. But some of them may have a real file. In this case you should rewrite it with symlink to gitolite hook.
I wrote a bash script which will do it automatically for you. Just make sure all path inside is valid for you
## 1. Stop server & resque
sudo service gitlab stop
## 2. Update GitLab
```bash
# Get latest code
sudo -u gitlab -H git fetch
sudo -u gitlab -H git checkout v3.1.0
# Install new charlock_holmes
sudo gem install charlock_holmes --version '0.6.9'
# The Modernizr gem was yanked from RubyGems. It is required for GitLab >= 2.8.0
# Edit `Gemfile` and change `gem "modernizr", "2.5.3"` to
# `gem "modernizr-rails", "2.7.1"``
sudo -u gitlab -H vim Gemfile
# Install gems for MySQL
sudo -u gitlab -H bundle install --without development test postgres sqlite
# Migrate db
sudo -u gitlab -H bundle exec rake db:migrate RAILS_ENV=production
```
## 3. Update post-receive hooks
### Gitolite 3
Step 1: Rewrite post-receive hook
```bash
# Rewrite hook for gitolite 3
sudo cp ./lib/hooks/post-receive /home/git/.gitolite/hooks/common/post-receive
sudo chown git:git /home/git/.gitolite/hooks/common/post-receive
```
Step 2: Rewrite hooks in all projects to symlink gitolite hook
```bash
# 1. Check for valid path
sudo -u gitlab -H vim lib/support/rewrite-hooks.sh
# 2. Run script
sudo -u git -H lib/support/rewrite-hooks.sh
```
### Gitolite v2
Step 1: rewrite post-receive hook for gitolite 2
```
sudo cp ./lib/hooks/post-receive /home/git/share/gitolite/hooks/common/post-receive
sudo chown git:git /home/git/share/gitolite/hooks/common/post-receive
```
Step 2: Replace symlinks in project to valid place
#!/bin/bash
src="/home/git/repositories"
for dir in `ls "$src/"`
do
if [ -d "$src/$dir" ]; then
if [ "$dir" = "gitolite-admin.git" ]
then
continue
fi
project_hook="$src/$dir/hooks/post-receive"
gitolite_hook="/home/git/share/gitolite/hooks/common/post-receive"
ln -s -f $gitolite_hook $project_hook
fi
done
## 4. Check app status
```bash
# Check APP Status
sudo -u gitlab -H bundle exec rake gitlab:app:status RAILS_ENV=production
```
## 5. Start all
sudo service gitlab start
