Migration

Submitted by Anonymous on

When upgrading OPush from version *a.b.c* to *2.5.3* or *2.6.0* a migration step will appear in logs (*/var/log/opush/opush.log*).

This migration impacts only [EhCache](http://obm.org/content/opush-ehcache) element.

The migration occures only one time when starting OPush (Jetty), and it will be skipped on next restarts.

**When an error occured during migration**

If EhCache memory configuration is too small, the migration will fail.

In this case, you have to raise EhCache memory, see [EhCache](http://obm.org/content/opush-ehcache) page for more information.

The migration will be reprocessed on next restart.

**NOTE** OPush will not be available until the migration ends normally.Sneakers
