Draft Document for Review February 7, 2020 3:15 pm 8464ch08_Migrate.fm Selecting the data Updating the applicable parameters If you select DFSMShsm-owned data, you can group your data as listed according to any or  all of the following items: You can select data based on data set name, by application, or by any other variable that you  can use in the automatic class selection (ACS) routines. You can also select data based on  type, such as System Management Facilities (SMF) data or DASD DUMP data. If you select DFSMShsm-owned data, review the ARCCMDxx member according to the  guidelines that are provided in 8.5, “Migrating DFSMShsm-managed data” on page 317 and  update the following definitions: For DFSMSdss, update the following definitions: GLYPH<SM590000> Migration data (DFSMShsm level 2) GLYPH<SM590000> Backup copies (user data, CDS data, or both) GLYPH<SM590000> Dump copies GLYPH<SM590000> Data Class (DC) ACS routines (if used) GLYPH<SM590000> Management Class (MC) ACS routines (if used) GLYPH<SM590000> Storage Class (SC) ACS routines (required) GLYPH<SM590000> Storage Group (SG) ACS routines (required) GLYPH<SM590000> For Basic Tape Library Support (BTLS), the unit parameter in the JCL GLYPH<SM590000> DC ACS routines (if used) GLYPH<SM590000> MC ACS routines (if used) GLYPH<SM590000> SC ACS routines (required) GLYPH<SM590000> For BTLS, the unit parameter in the JCL GLYPH<SM590000> SG ACS routines (required) GLYPH<SM590000> DC ACS routines (if used) GLYPH<SM590000> MC ACS routines (if used) GLYPH<SM590000> SC ACS routines (required) GLYPH<SM590000> SG ACS routines (required) If you use database data, such as logs or image copy, direct new allocations into the TS7700  by updating the following definitions: For data other than DFSMShsm and DFSMSdss, if you use SMS tape, update the ACS  routines to include the data that you want to move. You decide which data to filter and how  you write the ACS routines. You can also migrate based on the  UNIT  parameter in the JCL to  reflect the applicable unit for the TS7700. Although you are not overtly copying data in this option, ensure that you update the TMS  catalog or CDS to reflect the changes that you expect. Check the retention rules and limits,  and update as needed. If you change data set names when moving to TS7700, you must  validate changes against retention rules in your TMS. For more information, see 8.6,  “DFSMSrmm and other tape management systems” on page 325. Data movement that uses this option does not involve deliberate actions, such as  COPY ,  RECYCLE , or  DUMP . When you activate the ACS routines that contain the code for the TS7700,  all new data allocations for the data that you selected are written to the TS7700. Verify that  data is going where you expect it to go, and add code to the ACS routines to manage more  data as you see fit.
