Error description
Allow V900 queue-manager backwards migration from V910. Coexistence with a V910 queue-manager in a queue-sharing group does not require any PTFs to be applied to version 9. Additional backwards migration information is documented in the IBM Knowledge Center at: https://www.ibm.com/support/knowledgecenter/SSFKSJ_9.1.0/com.ibm .mq.mig.doc/q007698_.htm Additional keywords: MQ0910C/K toleration

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 9 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Enable backward migration to version * * 9.0.0 after a queue manager has been * * started with the version 9.1.0 code. * **************************************************************** PTFs for the backward migration APAR must be applied on version 9.0.0 queue managers prior to attempting fallback from IBM MQ for z/OS version 9.1.0. Attempting to restart a queue manager, which has been run with version 9.1.0 libraries, at version 9.0.0 without this PTF will result in abnormal termination of the queue manager with ABEND5C6 reason code 00C90D01. The IBM MQ for z/OS ISPF administration panels, CSQOREXX, are not updated by this APAR. The version 9.1.0 CSQOREXX application is able to connect to and administer version 9.0.0 queue managers and you are advised to use either version 9.1.0 panels, or those at the same level as your queue manager during the period of migration.
Problem conclusion
Code has been changed to allow backwards migration from V910 and coexistence with V910.
