I would like to upgrade Varnish 3 to 4 but without losing old cache(varnish 3 cache)
Could someone please help with this?
I replaced the VCL file and tried to reload getting VCL syntax error.
Message from VCC-compiler: Expected one of 'acl', 'sub', 'backend', 'director', 'probe', or 'import' Found: 'vcl' at ('input' Line 2 Pos 1) vcl 4.0;
Running VCC-compiler failed, exit 1 VCL compilation failed Command failed with error code 106 varnishadm -S /etc/varnish/secret -T 127.0.0.1:6082 vcl.load failed
Thanks in Advance.
