Switch Stacking / Firmware

[Rsbell]

I have a single switch currently in production running code: Cisco IOS Software, C3750 Software (C3750-IPBASEK9-M), Version 12.2(55)SE11, REL EASE SOFTWARE (fc3). I need to put in another temp switch for stacking, running code: Cisco IOS Software, C3750 Software (C3750-IPBASEK9-M), Version 12.2(55)SE10, RELEASE SOFTWARE (fc2). 

My question is, will this cause an issue when stacking both switches together?

Thanks

here is the steps :

1.  You have already  the switch running as  master;

2.   Attach the stacking cable to the rest of the member (in your case switch2)

3.  Power up the member2 switch.

Stacking Rules :

1.  Ensure all switches are running the same IOS version, same Feature Set (example IP Base);

2.  Once all switches are up, ensure you enable "switch n priority XX"; (which one to act as Master)

Suggestion on top adding to other post :

make sure you take backup of the config and do this task in maintenance window. since if you doing first time, to be safe.

My switch is not networked and connected to my PC via console cable - does it need to be networked to download my firmware file from tftp(my computer)?

I've tried different methods to access my tftp server with no luck.

#archive download-sw /overwrite tftp://10.12.3.105/c3750-ipbasek9-tar.122-55.SE11.tar

Keep getting - 

ADC-Visitor#$de /reload tftp://10.12.3.105/c3750-ipbasek9-tar.122-55.SE11.tar
Could not buffer tarfile...using multiple downloads

I believe I am downloading the correct firmware upgrade -
