*Make sure you view this [upgrade guide from the `master` branch](https://gitlab.com/gitlab-org/gitlab-ce/tree/master/doc/update/6.x-or-7.x-to-7.14.md) for the most up to date instructions.*
As of 6.1 issue numbers are project specific. This means all issues are renumbered and get a new number in their URL. If you use an old issue number URL and the issue number does not exist yet you are redirected to the new one. This conversion does not trigger if the old number already exists for this project, this is unlikely but will happen with old issues and large projects.
## Editable labels
In GitLab 7.2 we replace Issue and Merge Request tags with labels, making it
possible to edit the label text and color. The characters `?`, `&` and `,` are
no longer allowed however so those will be removed from your tags during the
If you [deleted the vendors folder during your original installation](https://github.com/gitlabhq/gitlabhq/issues/4883#issuecomment-31108431), [you will get an error](https://gitlab.com/gitlab-org/gitlab-ce/issues/1494) when you attempt to rebuild the assets in step 7. To avoid this, stash the changes in your GitLab working copy before starting:
* Make `/home/git/gitlab/config/gitlab.yml` the same as https://gitlab.com/gitlab-org/gitlab-ce/blob/7-14-stable/config/gitlab.yml.example but with your settings.
* Make `/home/git/gitlab/config/unicorn.rb` the same as https://gitlab.com/gitlab-org/gitlab-ce/blob/7-14-stable/config/unicorn.rb.example but with your settings.
* Make `/home/git/gitlab-shell/config.yml` the same as https://gitlab.com/gitlab-org/gitlab-shell/blob/v2.6.5/config.yml.example but with your settings.
* HTTP setups: Make `/etc/nginx/sites-available/gitlab` the same as https://gitlab.com/gitlab-org/gitlab-ce/blob/7-14-stable/lib/support/nginx/gitlab but with your settings.
* HTTPS setups: Make `/etc/nginx/sites-available/gitlab-ssl` the same as https://gitlab.com/gitlab-org/gitlab-ce/blob/7-14-stable/lib/support/nginx/gitlab-ssl but with your settings.
## 12. Optional optimizations for GitLab setups with MySQL databases
Only applies if running MySQL database created with GitLab 6.7 or earlier. If you are not experiencing any issues you may not need the following instructions however following them will bring your database in line with the latest recommended installation configuration and help avoid future issues. Be sure to follow these directions exactly. These directions should be safe for any MySQL instance but to be sure make a current MySQL database backup beforehand.
```
# Stop GitLab
sudo service gitlab stop
# Secure your MySQL installation (added in GitLab 6.2)
sudo mysql_secure_installation
# Login to MySQL
mysql -u root -p
# do not type the 'mysql>', this is part of the prompt
# Convert all tables to use the InnoDB storage engine (added in GitLab 6.8)
SELECT CONCAT('ALTER TABLE gitlabhq_production.', table_name, ' ENGINE=InnoDB;') AS 'Copy & run these SQL statements:' FROM information_schema.tables WHERE table_schema = 'gitlabhq_production' AND `ENGINE`<> 'InnoDB' AND `TABLE_TYPE` = 'BASE TABLE';
# If previous query returned results, copy & run all shown SQL statements
# Convert all tables to correct character set
SET foreign_key_checks = 0;
SELECT CONCAT('ALTER TABLE gitlabhq_production.', table_name, ' CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;') AS 'Copy & run these SQL statements:' FROM information_schema.tables WHERE table_schema = 'gitlabhq_production' AND `TABLE_COLLATION`<> 'utf8_unicode_ci' AND `TABLE_TYPE` = 'BASE TABLE';
# If previous query returned results, copy & run all shown SQL statements
# turn foreign key checks back on
SET foreign_key_checks = 1;
# Find MySQL users
mysql> SELECT user FROM mysql.user WHERE user LIKE '%git%';
# If git user exists and gitlab user does not exist
# you are done with the database cleanup tasks
mysql> \q
# If both users exist skip to Delete gitlab user
# Create new user for GitLab (changed in GitLab 6.4)
# change $password in the command below to a real password you pick
mysql> CREATE USER 'git'@'localhost' IDENTIFIED BY '$password';
# Grant the git user necessary permissions on the database
mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, LOCK TABLES ON `gitlabhq_production`.* TO 'git'@'localhost';
# Delete the old gitlab user
mysql> DELETE FROM mysql.user WHERE user='gitlab';
# Quit the database session
mysql> \q
# Try connecting to the new database with the new user
sudo -u git -H mysql -u git -p -D gitlabhq_production
# Type the password you replaced $password with earlier
# You should now see a 'mysql>' prompt
# Quit the database session
mysql> \q
# Update database configuration details
# See config/database.yml.mysql for latest recommended configuration details
# Remove the reaping_frequency setting line if it exists (removed in GitLab 6.8)
# Set production -> pool: 10 (updated in GitLab 5.3)
# Set production -> username: git
# Set production -> password: the password your replaced $password with earlier
