In WebSphere MQ for Windows Version 5.3, support for WebSphere(R) MQ SSL
is provided using Microsoft(R) SSL. In WebSphere MQ for Windows Version
6.0, support for WebSphere MQ SSL is provided using Global Security Kit
(GSKit) SSL. This means that WebSphere MQ for Windows supports only SSL in which certificates
are stored in a GSKit key database. Therefore, if you migrate from WebSphere MQ for Windows(R) Version 5.3 to Version 6.0, you need to migrate your certificates
from the Microsoft Certificate Store to a GSKit key repository.
The amqtcert (Transfer Certificates) command helps to do this (see WebSphere MQ: System Administration for more information on using this command). The chain
checker application, which is used to verify all the required certificates
are there before migrating certificates from the WebSphere MQ for Windows V5.3 store to the GSKit store, is available in WebSphere MQ V5.3
Fix Pack 10 (CSD10) or later.
Migration of security certificates from WebSphere MQ Version 5.3 to Version 6.0 is described fully in WebSphere MQ: Migration.
