Update screen: advise to disable apache while upgrading
|Reported by:||matt||Owned by:|
As to prevent errors, it is actually important to disable all tracking requests while the DB is upgrading (indexes deleted, created, etc.).
We should mention this clearly when printing out the command line to upgrade via shell (users that update via the UI don't need to disable their tracking since the DB size is probably small).
This tip was given by a Piwik user tracking 2 million visits per month, for whom update failed because tracking was still enabled, after stopping apache all went smoothly.
This ticket is probably
- updating screen Update in product, to explain to disable apache while running script
- Mention this in the online Update documentation as well
