Thanks John for answer, As per above document I understand we need to take backup of system and we need to execute 2017.2 setup.

This will be fresh installation of 2017.2 with new binaries.

Please confirm there will be no change on existing server(2017.1) once 2017.2 installation will be completed except version change as we have to do installation on existing server only.

ofcourse we have change license file.

Hi,

I have successfully upgrade cache instance. I have another query on cache migration. I have installed cache 2017.2 on new host and copy cache.cpf from my old system to newly build server to migrate database. I am getting below error while starting cache services.

Unable to copy file '/vcm/cachesys/cache.cpf53914' to '/vcm/cachesys/cache.cpf'
Error: Parsing CPF file /vcm/cachesys/cache.cpf - Shutting down the system
An error was detected during Cache startup.
 

Hi,

Please confirm if I follow below steps for refresh.

1. Export user permission on destination database.

2. Dismount source database and destination database.

3. copy cache.dat file from source server and replace on destination server.

4. Mount database on both source and destination server.

5. Import user permission.

Hi Robert,

Thanks for your answer. There is no issue with space as 56GB space available on mount point and access already exist to start cache services even we tried to start services with root but still getting same error.
