Hi Kalyan
1) All ABAP and JAVA based systems will re-registered in new SLD so all technical systems are populated after the registration.
If the Host name changes you have to re-register all the SAP systems to New SLD
2) I know i need to fix Java based applications which use JCO connections manually. I will fix them after we migrate to new SLD
After migrated or change the new SLD you have to change the JCO connections
3) PI is using local SLD and hence all business systems/technical systems are in PI development system already
PI tightly integrated with SLD,
All SAP Dev systems can be pointing to DEV PI,
All SAP Qas systems can be pointing to QAS PI,
All SAP Prd systems can be pointing to PRD PI
4) I will setup a bridge forwarding from PI Development to PI Production so all PI artifacts get populated into production.
Its not require to do the bridging. for all Central SLD bridge to Solution Manager for LMDB.
