We recommend migrating directly to one of the latest stable releases of WSO2 Identity Server (i.e., version 5.6.0 or a later version). For instructions on migrating directly to a later version, see Upgrading From an Older Version of WSO2 IS.
The following instructions guide you through upgrading from WSO2 Identity Server 5.3.0 to WSO2 Identity Server 5.4.0. In this topic,
<OLD_IS_HOME> is the directory that Identity Server 5.3.0 resides in and
<NEW_IS_HOME> is the directory that Identity Server 5.4.0 resides in.
