SLD to LMDB synchronization error- cim model mismatch

Question

Hello All,
In system preparation, we have configured the SLD and in the setup LMDB step we have added this SLD for synchronization to LMDB. Once we activate the synchronization (full sync) we first get a message "LMDB is on cim model 1.6.31 and SLD is on 1.6.37.Please confirm if you want to update LMDB to cim model 1.6.37." I clicked YES for this. Then it starts a job SAP_LMDB_LDB_0000000001 in the ABAP stack. However this job is getting cancelled with below message:
An exception of class CX_LMDB_CIM_ERR occurred
Classes for sync do not match: source model version 1.6.37, target 1.6.31
Can anyone advice what can be done to resolve this situation? Just FYI, This is not a new implementation there was another SLD that was connected to the LMDB earlier, however that stopped working due to a version mismatch. So now I am trying to sync the LMDB to a new SLD.
Thanks,
Anilraj Menon

Hi Anilraj,
When switching Your CRsource for the SLD/LMDB sync on Solution Manager, SOLMAN_SETUP You have to be very carefully as this is not a standard operation as such. You need to make sure that You don't have pending changes in the LMDB sync from the old SLD.
Furthermore, You should use the template in Solman_Setup, system preparation, step 5.2 --> click on "Advanced", and in actions, You should set the CRsource to the new SLD.
But please remark, this could lead to some inconsistence in Your LMDB thus the need to have no pending changes in the LMDB sync (You can see if there are any in the very same GUI where You set the CRsource - look in the "Status Details" pane: "Number of Source Changes Pending". This figure should be "0".
Also have a look on the blog from Wolf Hengevoss. I guess this adress Your exact problem:
