## Selecting the data 

If you select DFSMShsm-owned data, you can group your data as listed according to any or all of the following items: 

GLYPH<SM590000> Migration data (DFSMShsm level 2) 

GLYPH<SM590000> Backup copies (user data, CDS data, or both) 

GLYPH<SM590000> Dump copies 

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. 

## Updating the applicable parameters 

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: 

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 

For DFSMSdss, update the following definitions: 

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) 

GLYPH<SM590000> For BTLS, the unit parameter in the JCL 

If you use database data, such as logs or image copy, direct new allocations into the TS7700 by updating the following definitions: 

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) 

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. 

## Updating the tape management system 

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. 

## Watching the data move to the TS7700 

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.
