# Upgrading from older maddy versions
|
|
|
|
It is generally possible to just install latest version (e.g. using build.sh
|
|
script) over the existing installation.
|
|
|
|
It is recommended to backup state directory (usually /var/lib/maddy for Linux)
|
|
before doing so. The new server version may automatically convert DB files in a
|
|
way that will make them unreadable by older versions.
|
|
|
|
Specific instructions for upgrading between versions with incompatible changes
|
|
are documented on this page below.
|
|
|
|
## Incompatible version migration
|
|
|
|
## 0.2 -> 0.3
|
|
|
|
0.3 includes a significant change to the authentication code that makes it
|
|
completely independent of IMAP index. This means 0.2 "unified" database cannot
|
|
be used in 0.3 and auto-migration is not possible. Additionally, the way
|
|
passwords are hashed is changed, meaning that after migration passwords will
|
|
need to be reset.
|
|
|
|
**Migration utility is SQLite-specific, if you need one that works for
|
|
Postgres - reach out at the IRC channel.**
|
|
|
|
1. Make sure the server is not running.
|
|
|
|
```
|
|
systemctl stop maddy
|
|
```
|
|
|
|
2. Take a backup of `imapsql.db*` files in state directory (/var/lib/maddy).
|
|
|
|
```
|
|
mkdir backup
|
|
cp /var/lib/maddy/imapsql.db* backup/
|
|
```
|
|
|
|
3. Compile migration utility:
|
|
|
|
```
|
|
git clone https://github/foxcpp/maddy.git
|
|
cd maddy/
|
|
git checkout v0.3.0
|
|
cd cmd/migrate-db-0.2
|
|
go build
|
|
```
|
|
|
|
4. Run compiled binary:
|
|
|
|
```
|
|
./migrate-db-0.2 /var/lib/maddy/imapsql.db
|
|
```
|
|
|
|
5. Open maddy.conf and make following changes:
|
|
|
|
Remove `local_authdb` name from imapsql configuration block:
|
|
```
|
|
imapsql local_mailboxes {
|
|
driver sqlite3
|
|
dsn imapsql.db
|
|
}
|
|
```
|
|
|
|
Add `local_authdb` configuration block using `pass_table` module:
|
|
|
|
```
|
|
pass_table local_authdb {
|
|
table sql_table {
|
|
driver sqlite3
|
|
dsn credentials.db
|
|
table_name passwords
|
|
}
|
|
}
|
|
```
|
|
|
|
6. Use `maddyctl creds create ACCOUNT_NAME` to add credentials to `pass_table`
|
|
store.
|
|
|
|
7. Start the server back.
|
|
|
|
```
|
|
systemctl start maddy
|
|
```
|
|
|
|
## 0.1 -> 0.2
|
|
|
|
0.2 requires several changes in configuration file.
|
|
|
|
Change
|
|
```
|
|
sql local_mailboxes local_authdb {
|
|
```
|
|
to
|
|
```
|
|
imapsql local_mailboxes local_authdb {
|
|
```
|
|
|
|
Replace
|
|
```
|
|
replace_rcpt postmaster postmaster@$(primary_domain)
|
|
```
|
|
with
|
|
```
|
|
replace_rcpt static {
|
|
entry postmaster postmaster@$(primary_domain)
|
|
}
|
|
```
|
|
and
|
|
|
|
```
|
|
replace_rcpt "(.+)\+(.+)@(.+)" "$1@$3"
|
|
```
|
|
with
|
|
```
|
|
replace_rcpt regexp "(.+)\+(.+)@(.+)" "$1@$3"
|
|
```
