# Migrating from Prior Versions

To migrate from your current Adabas Cluster Services version to Adabas Cluster Services 8.6, complete the following steps:

1. Shut down all nuclei in the cluster and the ADACOM subtasks for the (SVC) / DBID set. Run Adabas ADARES PLCOPY and ADASAV SAVE utility operations as necessary for your installation. For more information on these utility functions, refer to your Adabas documentation.

2. Replace the load library in your existing installation with the library supplied by Software AG containing the Adabas 8.6 SP1 (ADA861.LOAD) data set. Apply the zaps delivered with Adabas 8.6 SP1.

3. Install the Adabas 8.6 SP1 SVC if you have not already done so.

4. Run the ADACNV utility with TOVERS=86 to convert the database to version 8.6 format. For more information about the ADACNV utility, refer to the Adabas Utilities Manual.

5. Restart the nuclei in the cluster.

#### Migrating to Higher Service Pack (SP) Levels Later

To migrate from one SP level of Adabas Cluster Services 8.6 to a higher SP level (after SP1), it will usually be possible to shut down the affected components (Adabas nuclei, ADACOM task, Adabas SVC) on one system at a time, upgrade them to the higher SP level, and to bring them up again, on one system after the other, without ever shutting down the entire cluster.

Should that not be possible for a particular new SP level, it will be clearly indicated in the release notes for that SP level and instructions will be given on how to upgrade and activate the new SP level properly.
